First off, they do work. For light work or picking up loaded pallets or whatever else your tractor can handle in terms of weight. Now the caveats, there is only a single connection point for securing the fork to your bucket and literally, it is a tiny single point. There is no plate underneath the bolt that you secure to the bucket. This is a problem because now it is a pivot point and it is a pain to securely tighten the fork down (hence why the 4 of 5 stars for sturdiness, you can never secure it tight enough, where they will not pivot). So unless you approach and fork straight on, you run the risk of bumping and adjusting the fork, so it is no longer straight. I wished they would have included a plate with the single bolt as they do with the two-bolt system. It would be safer and run less of a risk of the fork twisting on you. Now, the advantage of them not installing a stabilizing bar between the two forks it allows you to adjust your width as needed and is easier to store and move, so bonus on the forward-thinking, plus this set is half the price. But again the biggest issue is there is no plate to help keep the fork from twisting on the single bolt connection pair of forks. But they do make a model with an adjustable stabilizer bar and the secure points with the plates, but it is also twice as much. For the PRICE point and what the forks can do, it's more limited to what your bucket and your tractor can do. I installed my pair on my JD 790, they work great, and besides the issue mentioned they work great.
