Pros looks  nice and not cheap. Flames and heater work well. Remote is a plus. 
Cons predrilled holes slightly off but my bf worked around it. He is good at putting things together, and said it should have been easier.
Time for him to build it was over an hour or more. He was frustrated with holes not lining up better. 
All in all, it is worth the on sale price of 150 from Brad’s Deals online, but not regular price of 500. The insert with glass front, heater, realistic flames is where the value plays in. The particle board covered with white hardwood veneer could be improved though.
