Review on 🐟 HONBAY 20pcs Aquarium Black Sucker Clip: Efficient Airline Tubing Holder with Suction Cups by Roberto Smith

Pros: They have excellent suction power. They seem to be holding up very well. Cons: They come in two separate pieces that you have to put together and can be tricky if you're trying to put them together with just your fingers. I gave 4 stars just because they are included. two separate pieces and difficult to put together without the help of pliers. With that said, I quickly thought of using needle nose pliers to hold the clamp and using my thumb to press on the inside of the suction cup to firmly squeeze the connection of the two pieces together. See photo for reference with pliers
