Picked this up for my dental office to meet the eyewash station OSHA requirement. It was relatively easy to install if you have the right adaptersfittings to hook-up to your cold water line. I have 2 problems with the design: 1) The fit of the unit in the base is poor, so the entire top portion wobbles within the bottom ring. The black handle tapers at the base, so there is about 14 of play between it and the base ring. Because of this, the unit leans slightly over to the side. 2) The two flip lids on each eye spout do not clip or snap into place. This is probably a design feature for quick access to water, but with the leaning of the unit (as mentioned above), one of the lids flops open while the other one stays closed. My two issues are mostly cosmetic, but I'm very particular about that sort of thing. I've seen this same eyewash station in other offices and the fit at the base seems to be much better, so maybe I just got a bad handle. I'm fine with the unit overall because it functions and meets the requirements it's supposed to.
