Have had it for a month now. Bought 3 x 18 double depth and got the 2 foot upgrade, so 3 x 20. Medium speed.
Set up was about an hour. Recommend tweezers to separate the double side tape, otherwise easy.
It seemed a little cheap coming out of the box, but fear not. It looks good once set up and It rolls great. Rolls about 9 one way and 10 the other way.
If you care about looks a lot the side bumpers wound probably give it an ever better look.
Would recommend.
