Pressure switch doesn't work consistently
584969
The laser is bright and the mount is solid.  The pressure switch works intermittently, and after cleaning the lens cover with a soft photo cloth, the beam has become blurred, instead of a dot, there is now an "x".  This remains even after subsequent attempts to clean the lens cover.  I'm looking to see now if I can replace the pressure switch, and lens cover (front screw on cap) to restore it to how it should be..

Once it locks in, I start turning it, it slips off to often. I must grip it really tight to make it work

It works 60% of the time, but the 40% time it doesn't work makes me wonder what's the point of having it. Only once or twice a day it stops responding makes me want to use a regular switch instead...

The clicker doesn't always work. Or maybe I have to press more firmly. Haven't quite figured it out, but I noticed inconsistency.

This only works well some of the time. There is no power switch so the device is always on. At times it would lock up and freeze and I would have to reset it by unplugging all cables and starting over. This happened too frequently and I eventually switched to one with a power toggle and with more manual controls.

I am disappointed because it does not hold pressure beyond a certain level, or maintain it. The seal mechanism is finicky and screwing the lid on resulted in nicks to the mouth of the plastic cannister which interfered with the O-ring seal. Unfortunately when I called Chapin I was told that the sprayer was not meant to hold pressure. I like the device, but the problem prevents me from using the device as I had hoped and I have to re-pump it frequently. I am hoping to find a solution to the O-ring seal problem but I wish I could have exchanged or returned the sprayer. I will have to try to re-surface the cannister opening to repair the seal mechanism; I had to do a lot of research into O-ring physics to figure that out.

I cannot change the settings. The water pressure is great, so I really would like to find the solution. It may have to be returned. The instructions say some models have a small lever, or push button. This one doesn't have either. The plastic piece between the chrome pieces is loose, so that doesn't spin to change settings. It's frustrating!

Title pretty much says it all.  Great water mover, but not especially reliable.  The hose connection is particularly prone to failure (buy a spare with the pump) and tends to slide off under pressure (I finally screwed it on).  Although it's supposed to start automatically, mine has never been especially reliable, so I used two and hope for the best.

The on/off pause switch doesn't fully turn water off.

Doesn't work well on iPad. Have to use a lot of pressure.

It works nicely, but the pressure isn't as good as other faucets. Overall I am not satisfied with this.

I had one of these in the past, it was alright because it actually clicked when enough pressure was put in. Ordered this one, and it doesn't click. Just goes straight in and it's impossible to get consistent results. Can't return it, can't use it. Waste of money.

Not a bad light, but the switch began being intermittent.  I traced it to the switch itself and not any contact by taking it apart and measuring the resistance at the switch terminals.  The switch simple does not toggle correctly with each depression  --- when it is on resistance is less than 1 ohm, but it most often it does not successfully switch on and remains at nearly infinite resistance.  I never liked that the switch on this flashlight required so much pressure to depress, either.  The Mag lights have much nicer to operate switches. As the switch is bad, this flashlight will be recycled.

the pressure switch on this light quit working after only a few times of use.  the cord to the light is not very secure and I assume that has to do with it not working anymore.

Although it looks nice and the water heats quickly - the switch that's supposed to flip once the water boiling doesn't work consistently. I will have to follow this up with the manufacturers. :o(

We received it in a timely fashion however, it worked one time, then would not go above 20 PSI. We callrf their tech support and they shipped us out another one. Told us to keep the first one and use it for parts. We received the new one is a timely fashion, however, it does not work as well. It will run for a second and then not go above 40psi . The tank will not refill automatically, you have to turn it off and then back on. So, my husband is calling tech support again. So I would probably not recommend this, unless you like calling tech support a lot.

I really want to love this product but in all honestly it's a hit or miss.  We purchased two for two bathrooms on the bottom floor of our house.  One works great, the other kept turning on during the night and we ultimately had to take it out and replace it with a regular switch so that one switch that ended up working cost us 2x the price.
