We've had the fire pit for about a year now.  It's a nice fire pit for the money, however after a few months of usage in the spring and summer, the knobs are now kind of stuck.  We're having trouble turning it on and have had to bang on it.  We will see how it is once we open it back up this spring.  Hopefully it will be an easy fix.  We did   replace the lava rocks with glass for a more contemporary look.  Update 3/29/2019:  We just removed the cover to the fire pit for the spring/summer season.  The paint is chipping everywhere and it is impossible to turn on.  We got one good season out of it and the warranty is one year.  We've had it for a year and a half.  We covered it EVERY SINGLE night.    Wayfair will not replace it and we now have to go to the manufacturer.  I'm going to assume that they will not do anything about it, too.  I will update my review if they do.
