AI have ordered three of these for LEGO displays, and all three have been slightly different. Two came with a battery LED light, one without. One came with a grooved base, the others are flat.Assembly is super simple, maybe I got very different kits than others here have received. Agree it's pricey for what you get though.It was almost as expected. But the holes in the top piece are too small and i had to use a small file to make them big enough and in that process the surface was scratched and it has finger prints and smudges all over it now that are hard to take off. For about 50$ plus tax, I was expecting a product that was atleast manufactured correctly. Also there is a lot of cut debris from the manufacturing process still on it which can cause scratches. If you buy this product file the holes on the cover to take out the curved edges and do it before removing the protection film. It could be made more sturdy but its not so bad once its together.Comme au musée!The box fits together well. The only tricky part is snapping the lid on. Consequently, the top is not easy to remove. But it suits my purpose well.I ordered 2 display boxes and have some problem with one of them. Contacted the seller and he was very helpful in resolving the problem. I’m not just writing a review for the product, which I find it simple & elegant, but also the after sales service.I purchased this item twice - the first one came defected where the plastic did not align and fit. The sides was sticking out and NOT engineered as the photos display. I returned the first one hoping I was just unlucky and got a detected one. I purchased it again and the same thing happened with the poor engineering of the product measurements. The base was also damaged with someone's finger nail prints all over the white case. Completely awful product. I do not recommend buying this.Particularly like the fact you can move the derailleur while it's mounted and it slides with the chain. Makes degreasing the drivetrain and servicing the rear mech a doddle. Any form of maintenance that needs the rear wheel off is now easy to do without the chain all over the chainstay.Good quality, as always, from Park Tool, but pricey compared to others available. Used for a return trip having had the bike on the roof for the event, I took the wheels off and put it in the boot on the way back. The Dummy Hub was easy to fit and kept the chain tension. However, as it only fixes to one side of the stays, any movement risks it pinging off, which it did twice. I now use a full size skewer type that attaches to both stays, also found on Amazon for less cost.As they say, 'you get what you pay for', or at least you hope you do and in this case they are spot on. Yes it does cost considerably more than most of the other tools of this type but it performs faultlessly and the build quality is excellent. The quick release is better quality than the ones on the wheels and they're not cheap wheels! Not sure if it fits 'Through Bolt' axles, but it works well on my road bike and my hard tail XC trail bike. Well done Park Tools.I don't know how I managed without this when cleaning my bike! It allows you to remove the rear wheel so you can thoroughly clean the chainstays, seatstays, seattube, rear derailier. Then clean the jockey wheels without the wheel being in the way. Simple and very effective. The only negative is that it is a bit overpriced for what it is. The parktool is the best option if you have QR and Thru-Axle bikes.Oh my goodness!I thought, honestly, that this would be a gimmick tool; so very pleased I was wrongFits in the drop perfectly and once the chain/rear mech is engaged makes shifting, cleaning and general maintenance to the rear mech and chain an absolute pleasureWell done Park Tool. I love it!!!
