This Gator rack delivers the quality what you would expect from the company. It's built rock-solid, has really nice wheels, which can be really helpful when the unit is full and you need to move it around. The there are only 2 small issues: it lacks a surface treatment on the small stands/legs, so if you have the rack sitting on a table, or such it slips and slides more easily than expected.
If the front and rear are removed, the butterfly handles move quite freely around, so they can be caught up easily in obstacles. I use it standing on it's side and this definitely needs checking to make sure you don't scratch the surface you're putting it on.
Other than that it's solid, quite light and easy to add or remove racks, so I give it a 5-star.
