Sterling Sold Diamond & Gold High Security Ground/Wall Anchor, Black, GA1

Good Design and build quality for the relatively low cost, easy to follow instructions (you will need a decently capable mortar drill and drill bit, standard hand drill won’t cut it) the supplied captive screws/bolts fitted easily and tightened well. Couldn’t be happier with the end result

Good quality

Hard to tell the exact size from the stock photos but it's bigger then you think. If you have the tools to drill an 18mm hole in concrete you'll be able to fit this. My only slight concern is that the eye is so big that if not positioned properly a scumbag could maybe get a bar into it and lever it up. Clever placement between wall and bike should prevent this. Ultimately one piece of security will not guarantee the safety of your machine but definitely a good addition to the system. Good enough value. I'm happy.

I had no problems installing this as per the video instructions on the product page. Used an SDS 10mm drill bit to make the pilot hole and a 16mm for the main hole. The bolts went in the hole with no problems - I handled them delicately but did not experience any of the problems some reviewers describe. I tapped them in with a rubber mallet to get them flush. Whole process took 15 - 20 mins and I was taking my time with it. It appears to be a very heavy duty item, and while I have not doubt that a thief with professional tools would get through this if given the time, but the reality is that the effort required would be prohibitive and that they would look for easier pickings elsewhere. Sold Secured diamond so the insurance is all valid anyway. Great price in comparison to other products too.

Really easy to install (just make sure you read the instuctons and have the right sized drill bits etc).Installed mine on my concrete garage floor. It's a bit tricky to get each of the 2 holes spot on, which you obviously need to do or you won't get both the both the bolts in the right place! I drilled 2 holes using a much smaller drill bit first to make it easier to get the bigger drill bit accurate enough, this worked on for me.Had to hammer each of the expanding bolts in a bit as i got it very slightly off, but they both went in in the end and everything tightentend up perfectly and it is really secure.Took me 20 minutes to install and would thoroughly recommend for anyone with expensive bikes/motorbikes. Very resonably priced too.

Needed an 'immovable' object to put in the shed for my e-bike. This does the job! Easy to put in and comes with the little ball bearings so you cant unscrew it once fitted.

You have to have one of these for your bike insurance to be Valid.

For such a basic device I was surprised that this ground anchor was granted a diamond rating at such a good price.
