Great price for the reels but this is definitely an economical reel. I've been buying very high quality roller skates for many years, but I've found that I've built several carts that rarely move but still need to be on wheels. Anyway, I decided to give these videos a try. Structurally they are solid, the wheels are tidy, the bearings are ok. The case of these wheels is a lock. The lock cannot be unlocked with the foot when engaged (at least with boots on). So plan to bend down to unlock it. The lock prevents the wheel from turning, but hardly keeps the head from turning. So if you put them on a cart with all four casters fully locked, it won't roll anywhere, but the cart will still shake from side to side. This does not make the project fully stable and in some cases it can lead to a real problem. High-end reels don't have this problem, but of course you pay for it. After all, these reels are a good deal for the price. Use them for less important business projects. However, don't expect them to compare to higher quality videos.
