Very convenient good product. The only drawback is that it needs to be in the right sink with the right faucet. If the faucet extends a little too much into the sink area it will shoot water over the sink on to the floor. But in the correct sink and faucet it works great. I have two of them installed in my facility.We had a terrible time with this Eye Wash Faucet. First, the adapters for mounting the faucet to the water tap would not would not work. After having unsuccessfully gone to several plumbing supply outlets to try and locate the correct adapter I called the manufacturer to get one. They were very cooperative and sent me on for free. The only problem, it didn't work properly. Finally, after having gone to five different plumbing supply places we found one that leaked. The second major flaw with this faucet is it does not spray water high enough to reach your eyes all the while you bang your nose and forehead on the faucet. We then tried to purchase the eye extenders from the manufacturer but the cost was prohibitive and would have take 4 to 6 weeks to get. We finally went to another brand that was only slightly more expensive but worked correctly the first time we installed it.Purchased two Eyewashes to try them out.I knew they would be great with the first hook-up, I did'nt get my hair wet with a big blast of water as with the old ones, so, I purchased three more. Well satisified with this product.The purchase of the Guardian EyeSafe Faucet-mounted eyewash station has proven to be a cost effective means of adding safety to any work room enviroment. The EyeSafe installs easily, especially to an American Standard Colony Soft Double-Handle Laundry faucet. The EyeSafe is easy to turn on water flow for eye cleaning situations.Perfect product for our 43 bed Assisted living Facility. Performs at monthly QA testing's exactly as promised. We turn both the hot and cold water on to achieve a taller stream but it might just be our water pressure. Easily installed.It will do for now you need really strong water pressure for this to work properly I guess.I have used this eye wash before. it serves it's purpose. Company is easy to work with. Order was proccessed quickly and accurately.These eyewash station are perfect since they do not interfere with the operation of the faucet. You use the faucet as usual & if you need to use the eyewash you simply pull the lever located right in the front. Very good design.
