Query: What a piece of junk!

I bought 3 of these fireplaces. The regulators all stopped working almost immediately. I contacted Coleman, and was told to send the regulators in for replacement. It's been 3 weeks, and all Coleman can say is that "we"re processing the paperwork", which I assume means, "We can't fix these darn things or find replacements for them"! What a rip off! I will never buy another Coleman product!
