Review on Lee's Original Undergravel Filter - 20L/29 Gallon - 12 x 30-Inches by Sharon Hill

No no no. Don't waste money. The plastic of this riser product is fragile like glass. Two different parts of the risers were broken on arrival. I glued them together super and hope it works but so far very dissatisfied with the quality (or lack thereof) of this product. I would NOT recommend it and if the return process was quicker and easier I would just send it back and buy something else. Unfortunately, our tank is already set up and ready to build and I don't have time to wait for a new one, so let's settle for what has arrived. Good luck building. "Instructions" is only on the box and didn't help much. The photo shows the two parts after I glued them together.
