Very easy solid wheel lock.
Fits caravan wheel well. easy to fit once you get the knack on what way you need to attatch depending on how the wheel is lined up. Very solid and at a good price.

Not a universal fit. Doesn’t fully fit my van.
This was a faff to fit. The instructions are not very helpful and some of the YouTube videos don’t include how to know if you need the space washers. In the end it was a case of half knowledge plus trial and error. If you are buying a caravan I recommend buying the wheel lock before collection of the c’van so you can ask the vendor how to fit it - perhaps they’ll do it for you! I’m female so that’s my excuse, but my husband who was helping wasn’t sure either.Next important thing to know is that it is NOT a universal fit. doesn’t perfectly fit the Basecamp Plus alloy wheels. The distance between lock unit and bar is short by an millimetre or two. Why they make it like this, goodness knows, the slot could easily have been a mill. or two longer. Ideally it should go across the middle, but I could only get it to fit by putting the bar through a closer spoke gap. This means some of the wheel nuts are exposed and could be removed! Had we known, we’d have measured it carefully and possibly sent it back, but by the time we realised, the sponge protection was already showing signs of use, so probably wouldn’t have qualified for a refund.Once set up it does seem to go on and off fairly easily.

Easy to use
I'm getting older and faffing about with the old wheel clamp was getting more difficult so I got the nemesis after someone posted about it in a forum. I'm so glad I did, once it's set up it's so easy to use. I left a site this morning in the rain and arrived home in the rain saved minutes at both end. It's not cheap but it should last for years so worth it.

Decent piece of kit.
Bought this to comply with the requirements of my insurance for the van. Have owned other types of wheel lock or clamps previously and this one is certainly the easiest to use. The AlCo device is too fiddly and really needs two people to apply whereas this is easily done by me alone. It's hard to give it five stars for value for money although in fairness it's very well constructed. The amount of material in it however doesn't warrant a price tag of over £100. Security wise it's a recommended product by most insurers but untill some tries and fails to steal my van I cannot give it an objective personal assessment. Having said all of that, of all of the products I have used or seen, this one seems to be the best.
