Do not use factory Direct SPA Covers. I bought a cover from them in 2007 with a 10 year warranty and they will not return my emails. The cover has bubbled and is no longer the color gray, now it is brown and staining the deck and steps. I sent them pictures of the damage and have gotten no response.

I will no I order from them again and I hope this input helps others from making the same mistake that I did. read full review »
