Question: is there an on/off switch?
Document: works well for its intention, I had to add a little attachment on my sink sprayer head to create an air tight seal ( like those flexable aerators)  use it to wash cats babies and small dogs in the sink
works awesome, but after a while of regular use the end that hooks to the sink stretches out and becomes loose. For the price though it does last quite a while, i plan on simply ordering a new one and tossing the old one out
way too short which makes it almost useless. sorry.
the item never hook up the tape, and makes water out flow every where. moreover I just open the bag for about one hour than the smell of plastic goes everywhere. Have to throw it out to avoid bad smell. This is the worst item I ordered on Amazon, so disappointed
i knew this sprayer would leak as i've used them before. i use this sprayer to rinse eggs. got just what i ordered.
good for washing the dog in laundry sink. Could be improved if it just has clip near the nozzle to keep it from moving around when you leave it running in the bottom of the sink.
We bought it so my wife can shampoo our small dog in the kitchen sink. Simple and inexpensive. Woks great! !
This thing gave me a sink sprayer. Just add a clamp so the water pressure doesn't blow it off. Adjusted correctly, it goes on and pulls off the faucet easily.
This slips easily over water spout and doesn't fly off when you turn water on.
This hose fits better than others I've tried and it just makes the job of washing my elderly mother's hair so much easier.The tap adapter fits on beautifully and the hose doesn't get tangled up!Love it and highly recommend it.
