Very happy with this extremely sturdy ground anchor, and also that I can move it at any time if I wish without having to buy a new one. Very good and clear instructions, easy to fit.

Easy to install, secure as anything I have ever seen - make sure you get the additional drill bit though, it is a quality bit - but makes the job a million times easier!

Highly reccomended!

I moved house recently and have a covered parking space so I shopped thoroughly for security that would keep my bike safe. I chose well. The double doofer is simple to install and works a dream with my very chunky lock!! I have no doubt that the efforts it would take to break my bike out would require attention being drawn to the theft if they even managed to get it out!! Great product, great price, great choice. Thank you.

This product comes with everything you need to make sure it is fitted properly and because of that is easy to fit. The system looks very secure and I am very happy with it. This firm has excellent customer service. If Carlsberg were to go into this line of business - they could not do better!!

A simple but effective design, very heavy duty.
I installed it in under 10 minutes (made a cardboard "stencil" of the holes/lock first, which made installation a doddle).
Works great with my 16mm chain, and I'm pretty sure the house that's attached to it now is pretty safe. As well as the bike, of course.

A great product and comes complete with all fittings. This is a stronger Anchor than others I have seen and a major plus is you can re-locate it as many times as you like, unlike others. Very prompt delivery and very good communications. I have now purchased quite a few products from this firm, and I’m sure I will purchase more. I highly recommend if you want quality and service.

Exceptionally easy to install with a cheap corded, non-SDS drill and I have little experience in such things. Very secure to the ground, as long as a chain is running through the anchor no-one is getting under it for leverage. Being able to move it wherever for the price of some replacement expander bolts is brilliant. I'm not sure why you'd go for the permanent anchor when this one is this good.
[Pragmasis Comment: The Torc anchor is cheaper and can also be used with resin fixings, which can be stronger when used in suitable concrete. In brickwork, there is less of a distinction other than the price difference. The Double Doofer does require a close-fitting chain to be left through the anchor at all times in order for it to remain secure, so there is a minor additional complication with its use.]

Superfast delivery on this fantstically engineered ground anchor, you can see and feel that it's a top quality item, just its presence is likly to make anyone thinking about attempting to force it off for life, I fitted it to secure my Tiger800, the fitting process is very easy just follow the detailed instructions and you wont go wrong, i would say even for a novice DIY'r it would only take half an hour, love the fact that it can be used in more than one location, if you are looking to secure your beloved bike then this is the bit of kit you need. 5 star excellent product

Very nice strong ground anchor, can sleep soundly at night knowing my bike is secure outside. Product was very well packaged and received very quickly! Great item.

I bought the Double Doofer Deal for my new bike, and the service and delivery were very fast, I was even e-mailed on a Sunday to confirm some details. The Doofer, chain and lock are exactly as described, and the fitting kit had all I needed (except the power tools!)

I have placed two orders with SFB recently, and in both cases their customer service has been fantastic. David was very helpful and attentive to my needs. 5 Stars is not enough.

Great product, excellent service, delivered very quickly

I have just bought some ground anchor bolts and wanted to write a review because the service I have received has been excellent and so efficient. My initial contact was dealt with in detail to make sure I was buying the right product and despatch was dealt with instantly. well done you deserve a great review

Fantastic service from start to finish, would highly recommend!

I dithered over which anchor to buy for quite a while, but so happy I chose this one. Service, Delivery and Product are all high class. Installation very straight forward, once I'd hired a drill powerful enough to conquer the garage floor! I'll be back for a 19mm chain in the new year. Thank you David!

Having installed the Double Doofer I can confirm that it's a very high quality, well made security device. Any prospective thieves would probably need a JCB to pull it up. Easy to install yourself, but you need a powerful drill.

The Double Doofer was easy to install and looks impressive. I can't find any fault with the product or installation instructions. I'm using it with an 16mm Protector chain and a Squire SS65CS padlock. Just the sight of them alone should put any thief off.

Recently bought one. Service was excellent really helpful with the choice of products and their compatibility. The products came quickly, were easy to fit as it took about 10 minutes and is really easy to use on a daily basis.

I bought one of these Double Doofer ground anchors to use with a 19mm Protector chain and an Abloy 362 padlock. The whole package is superb. You get VERY clear instructions and all of the parts (barring a power drill) that you need to safely and securely fit the anchor. The guys at Pragmasis even go so far as to put a piece of tape round the supplied drill bit to indicate the depth you need to drill to. Little details like that make you happy that they are also concentrating on the really important stuff like quality of steel and welds. I will cheerfully shell out for Pragmasis gear in future.

So this is me, again, being 100% satisfied with a Pragmasis product. This thing weighs a ton, which is great and its sure as hell secured to the floor of my garage. It looks great, doesn't get in the way and gives me peace of mind. It was easy to install, though a more powerful drill would have made the job quicker! I highly recommend this product and the team at Security for Bikes - thanks a lot guys!

Bought to replace a Torc Ground Anchor as the result of a recent house move. Really solid item which is extremely well finished & if looks are anything to go by, will be completely effective.
Impressive delivery time too.
Now feel completely protected again!

This is an amazing product, the attention to detail is very high.
The product in itself is heavy steel and nicely finished. What really brought me to the highest satisfaction is the mounting kit that comes along: everything you need is in the package and it is of the highest quality. Very satisfied!

This thing is heavy duty (good way)
Got it to attach it to the garage floor to secure two bikes.
With one plate and a 16mm chain through, there is no option to remove the cover, so it will stay put until I decided to take it out.

Great customer service, swift replies to emails with advice and the ground anchor is great.

Fitting kit and instructions were excellent. I did manage to burn my cordless drill out though!

Fits Almax Protector IV 19mm chain nicely.

Cheers! Ben

I have been using two double doofer ground anchors and chains for my bikes for a couple of years. They are easy to fit, solid and easy to use.
When I had to move them recently, there was no problem obtaining the new fitting kit I needed.
The service I have received from Pragmasis through their website, by email and over the phone has been exceptional.

Great customer service and communications. Arrived on time and with all the bits, even a drill bit, to fit. Care needed to ensure you get the holes correctly drilled - I recommend a pilot hole first. Works like a dream once fitted. Recommended!

I had been very impressed with the products a few ago having met the guys at the NEC bike show. Recent telephone support was a great help and ensured that I ordered the correct parts first time. Order confimations and general Comms were personal and gave great confidence when spending so much money. Kit contents and attention to detail in the instructions are perfect. Easy to fit and very pleased with the result. Very highly recommended. I have down loaded the Sold Secure certificates and will store then should I ever need to make a claim. Not really likely as the protection is of epic proportions when coupled with the 16mm link chain to the 13mm main loop. Top work guys. Huge thanks.

I've just become aware of Pragmasis, but on the back of their no-nonsense honest website I have bought 3 products (The Double Doofer, the Torq, and a Protector 16mm chain). I was very impressed with the speed in which the goods arrived and when they did, I was even more impressed as to the detail that the team had gone in to in making the installation an absolute breeze. Superbly clear instructions and an even better install kit. Every bit you could ever need right down to tape on the supplied drill bit so you knew how far to drill. 5-Star service accompanying 5-Star products. They've been a pleasure to deal with

Already have the Torq Anchor for several years. My son has now moved out into rented accommodation and so brought him the Double Doofer. Both are top quality design and manufacture and the service was excellent too, couldn't ask for more.

In search of an excellent high safety system for securing my bike I found Pragmasis. I am very lucky because it seems there is nothing comparable in whole Austria.
The double doofer ground anchor together with the massive 19mm protector chain and the SS65CS-XLN padlock is a really highest-level protection system. And I think as long as there are so many other bikes less or not additional secured at all, the thieves will choose those bikes instead of mine.
The ground anchor came perfectly packed together with the entire fixing kit. After I fixed it to the concrete floor, I pulled one end of the heavy 19mm chain through. Then I put a SFB RoundLock RL21A through this end link, to make it impossible to pull it back. The RoundLock together combined with the 19mm chain end link is too big to pass the double doofer anchor. Therefore, I have the whole length of the chain available, and don’t need the chain in double length (the chain is really heavy!). On the other end I use the Anti-Pinch Pin together with the SS65CS-XLN padlock to lock the bike.
PERFECT SOLUTION, thanks to Pragmasis for the ideas, the implementation and the highest quality!
Customer service by David Briggs is excellent and very friendly!
Absolutely recommended company!
