ALEGI Aquarium Air Pump Accessories with Non-Return Check Valves,Air Control Valve for 3/16" Aquarium Tubing (6 Check valves+6 Control Valve) (Red)

Have to come back with a update does not work have to keep trying to use

Good quality. Everything was packaged well. They do exactly what they are supposed to and pretty inexpensive

These work well however I believe it's limiting the air flow from my pump. None the less the product works as it should and I have no worry of back flow.

As advertised

This air pump is virtually silent. it puts out a good amount of air. I don't yet know about the longevity but I'll only be using it for intermittent operation. Very compact. I've got it sitting on the filter of my hang on back filter. I'm using it on a 1 gallon tank for hatching fish eggs. I'll never buy any other kind of air pump.

Cheap, works ok, but not very good quality. I bought this for the flow valves. The reverse flow restrictors are not trustworthy, built to cheap.

Easy to push on tubing and no leaks.

WASTE OF MONEY. Do not buy, if you want to control the flow of water. These do nothing. No control at all.Used four of them, all of them bad, did nothing at all. TOTAL CRAP.

Bought a set, arrived broken (damaged shipping envelope). Second set arrived, look fine and seem to work fine. Check valve installed backwards didn't pass air (that's good). Closed control valve didn't pass air (also good). Correctly installed and opened pass air fine. Nothing leaking so far (about a month in).

2 out for 6 non-return check valve has a small cracks on them. still a great product over all. there is room for package improvement.

Bon produit

Not bad. I had one bad check valve in the bunch, and one bad T connector. 9/10 functional on both. The ones I have in use are working fine a month or so in.

Only 5 of each suppose to be 6 of eacj
