Unfortunately, there were major problems with the first delivery. We received a defective and clearly used carrier, sent in a lousy variables and torn packaging. After a complaint was the second carrier, which was then new. The assembly was a bit tricky, but doable. Unfortunately, the delivery was missing a part, which came after a complaint but quickly. Two wheels can be trans portiern well. With three wheels already requires skill and a little tinkering to fix everything well. All in all a reasonable support for this price. Anyone looking for real quality and usability, should rather resort to another manufacturer.
