This does a great job of walking up the stairs which is obvioulsy it's main purpose, however, if like us, you have a turn in the stairs, it can be a lot more difficult. The main issue is caused by this having 4 castors rather than the usual 2 bulky wheels, so to turn on the stairs you have to get the trolly back to its upright position which is easier said than done with anything heavy on it. I've also knocked a star off purely because this thing is really heavy already. Load it up with 150KG, and you're really going to struggle with it.
