5 or 6 years ago I bought 3 of these trolleys and I'm satisfied. They undoubtedly do what is required of them and at a very low price compared to what is the same in the market. I recently bought two more because the ones I had started to get damaged with constant use. The weakest point is the zip fasteners that break easily if you are not careful. The strong point is the wheels, they go over everything. Overall, for the price is an excellent buy if you consider that the material is not very sturdy and treats them with care.
I bought these to use with a pair of Mackie SRM450s. The first ones I had, the telescopic handles broke after about half a dozen gigs. Thomann replaced these under warranty, and I have been rather more careful about not putting too much weight through the telescopic handles - basically, don't lift the speakers using them. One of the internal straps has come adrift at one end but we can cope with that. As they're about a third of the price of the official Mackie ones, they are a good buy, and do their primary job of protecting the speakers perfectly well.
