Review on Upgrade Your Bathroom With Touchless Technology: Greenspring Automatic Sensor Faucet For Hands-Free Convenience by Kenkoy Braggs

We replaced the bathroom fixtures at our school with these because of COVID, hands free and all that. They seem to perform well, but a few points about installation:1. The weak point of this system seems to be the mix valve. It seems to be made of soft metal, and the threads are easy to damage when connecting the feed lines. Once damaged it’s gone.2. The design necessitates using the included feed lines. They are not standard type feed lines and don’t have the rubber washers those have. Replacing these may be difficult. Lines should be at least three inches longer.3. Connecting the main feed line from the valve to the faucet requires a tight fitting O ring in both ends. This does NOT come with the kit. If you don’t use an O ring it WILL leak. This is a blatant oversight on the manufacturer’s part.4. Since at some point battery changes are inevitable it would be nice to have an access panel that doesn’t use itty bitty.screws that get lost easily. Considering that this is a compartment with a water seal, it’s important to be able to secure it easily and reliably. I mean, it works, but it’s just something that can be an annoyance later.5. The stem can be a bit tough to tighten sufficiently. This is because it rests on top of the plastic plate covering the two holes in the vanity top on either side of the stem hole, and tightening too much will crack it. A metal plate or some sort of tab machined in the brass stem to prevent movement would be a big help.Overall, though, it seems to be a good compromise of quality and price. I suppose you could pay $300 and get something without the cons listed above, but that adds up really fast when you’re replacing 20 fixtures. It’s a trade off. Take your time with installation, maybe buy an extra valve and and feed lines in case something happens later.How does it hold up against constant use by school kids? I’ll come back and let you know.UPDATE:So far I've had to replace only one control box out of 12 units. It just stopped opening the flow valve, faucet would just drip slowly.UPDATE 2 (5/21): I noted before how it can be difficult to sufficiently tighten the spout enough to prevent rotation movement. Well, what ends up happening is kids play with it, move it around, and that ends up cutting into the cord for the sensor that passes through the hole in the sink top and rendering the faucet useless. Only solution I know of is either find a metal replacement plate and/or a silicone based sealant that will hold the spout in place and discourage twisting.Ultimately what is needed is a way to purchase individual replacement components, and I have yet to figure out how to do that.
