suction cup

These are fairly study feeling, yet flexible enough that I think it is going to work very nicely with my flexible fish tank tubing. The clips do not crack or snap off when pinched like cheaper ones I have used. Im satisfied.

Not much good or bad to say, they’re good for the price, I doubt they will stay on the glass indefinitely it happens that they come off cheap or expensive ones. If you need cheap black air line suction cups this will do the job.

These are a must for running air line tubing. It helps things stay in place. I wish it were all one-piece, sometimes the claw comes off the suction cup. Other than that, they're great.

Worked wonderfully

These are great for the price. Suction could be a bit better when not submerged in water but since dry suction is not what this was designed for I'm fine with it. Still works awesome.

They worked to help keep the air supply lines neat and tidy. However, they keep coming loose inside the tank.

Perfect size for what I needed. Suction is good. Blends in well.

First off, I only needed three. These suction cups fit great, have good suction and holds the hoses tight.
