kcrygogo 13 Plug Holes Coral Frag Rack Clear Acrylic Holder Aquarium Fish Tank Button Coral Reef Broken Frame Enhanced Suction Cup (2 Pack)

These have like a plastic cone over the suction cups that was impeding it sticking well. After taking it apart and removing the cone works fine but it’s easy to overload and then the shelf will slide down the glass.

100% Recomendado

The suction is not strong enough it falls off

These work really well. Some of the other plug holders just won't stick but these ones stay put. The suction cup has a knob on the back you twist to create suction so they really hold onto the glass. If you need plug holders I highly recommend these.

Love it works fine for price... So far so good. Keeps the frags out of the sand bed and keeps them away from other corals until you place them..or put them where they are going yo go

I’ve had mine in place for a few weeks and it hasn’t moved at all. I have a hammer, torch, two zoas, and a small leather on one. I read some reviews about them sliding down, but mine are on and feel secure.

I should have read all the numerous negative reviews before I bought these!!! I don’t think they even stuck for two weeks bore they kept sliding down the sides of the aquarium wall! I would wake up in the morning to all my frags tipped over, on top of each other and upside down in the sand! Not good! Wish I would have sent these back because they are worthless! In the trash they go!!

Placement needs to be perfect for the suction cups. But great value. Good quality, good size.
