I used this for distribution of human oxygen at home. I needed something to divert airflow down various tubes depending on were I needed oxygen. This worked nearly perfect. It's small and requires no assembly except if you want to use the suction cups which is nice for mounting. Air flow is excellent with no noise. Seems very durable. I really need more length on the inlet and outlets for hooking up oxygen connectors but a little cutting on the plastic oxygen connectors solves that issue. Holds firm and the value on/off is easy enough but might be difficult for people with fragile muscles in their fingers. This is the best solution I could find for diverting human oxygen at a reasonable price. Excellent!

These air flow levers work amazing and i couldnt operate my fish room without them, they're durable, look nice, and are just the right size to not be a pain to install, but not be too loose.

10/9/2023: have been testing for a while, and I LOVE this product! I didn't wanna buy another air pump when I came across these types of valves, and WOW! It works for both my tanks and it's not even loud (excluding air pump). It fits both my tubings and has some pretty strong power! That being said, you do have to adjust it to each sponge filter, one works perfectly fine but when you try to adjust it, the other filter stops. Otherwise, it's a great product! Anyone who has multiple betta tanks or ones with low-flow, I definitely recommend! Will be buying again if I get more tanks!

Quality is quite good.

Amazing! I'm now able to use 2-sponge filters with just one air-pump! Works great!

The valve isn't perfect but that was expected. Airflow isn't equal between each valve so you need to adjust accordingly. The suction cups stick well for me but the clips on them are mediocre. They will hold flexible standard airline tubing fine but anything thicker or with more resistance may give problems. 1 of the 3 check valves worked very well. The other 2 limited airflow a bit. Still, most check valves are a lottery and these 3 in general were much better than a pack of 4 black ones that I got from another seller. None of the items are perfect but at the price it's still worth a buy.

Works great well made

Nice quality 4-way gang valve. No leaks and valves are easy to adjust.

For some reason I assumed that 4-way valve was going to be made of plastic but it is actually metal. I was impressed by the use of quality materials on this product. The 4-way valve works excellently and is super convenient and handy for controlling my air pump output, I really love it. The suction cups are a bit weak and don't seem to want to stay stuck to the glass long term, but I am using them as extra security for keeping my air lines concealed under gravel. Since the gravel gives a lot of weight to hold it down anyway, I'm not too concerned about the suction cups. If I want good ones, I will just order a pack elsewhere. The the back-flow valve doesn't 100% guarantee protection of water back-flow (it works if it's angled just right but if its not, some water drips past.) I recommend that if you're going to rely on the back-flow valve in this set, test it out first (when its NOT connected to your air pump!) to make sure you have it set up in a way that it will actually work. I really only bought this set of tools because of the 4-way control valve and since that's the item that is perfect, I'm rating it a full 5 stars.

Works as advertised. Mine seals great

allows two separate air lines to run easily with adjustment on both

Works perfect for aquarium

Was missing the suction cups and non return valve hardware
