ESHOPPS Prodigy M Overflow Ultra Slim Overflow Box. 500 Gallons per Hour. for Aquariums 20 to 70 gallons.

I am so happy , cannot wait to install it .Looks pretty neat and a solid peace of art .Waiting for the plumbing .I did the plumbing to my metric pipes without the adaptors and it works fine, there is no way its coming off or leaking , I used extra glue. the only thing I don't like about the product (after about 5 months of use is that the back box lid keeps on bending !I will try to make a glass one .still 5 stars .thanks

This overflow leaked at its corner. I drained the tank and filled it back up it multiple times thinking I had misaligned something with bulkhead because the overflow looked perfectly fine. There's not a good way to hold the internal bulkhead and keep it from spinning while you tighten it down. I was doing a tank transfer and didn't have time to get a new overflow so I quickly patched the leak with superglue. The guide was a millimeter too small so, I had a fight to get the included drill bit go through the plastic first before I could even touch the glass with the drill bit. Overall I'm a kind of scared this whole thing is going to break and flood my house after seeing how poorly these acrylics are glued. Oh and to top it all off, the top warped over 2 days of having it on while the tank was running.

It arrived okay but the cover was missing. I had a local shop make me a new one for $10. Would have thought it was easy enough to check all the parts were included.
