Riser was out of round and hard to fit to base and lid.
The actual riser, base and lid are legit high quality and durable. I don't see these cracking or warping anytime in the next 30 years. Definitely reusable for the next tank. The kit however is not necessary in my opinion. I was missing one stainless steel screw which was no big deal cause I had similar extras. My tank was made from concrete with a lot of stone in it so I was unable to drill all the holes deep enough for the screws to tighten down all the way making some of them obsolete. No drilling is necessary. The sealer is good quality but you could just as easily use roofing tar/sealer in a caulk gun. The free shipping made buying from TGP worth it.
