Ask someone who independently installs fireplaces what they think of them, ask two or three professionals, the weird thing is that they all use the same expletive.
Their fireplaces look only vaguely like the brochures, you get simpler, knock-off versions when you buy.
If you need a design modified, they will be happy to charge you extra only to send you their standard size so you have to change your hearth etc. or send it back and wait push your project back a few months.
Both these things happened to me, plus they were generally lying to me and delayed me for many months until the fireplace arrived packaged from abroad, most likely China.
Chinese factories make high quality stuff these days, so buy direct, they are much more honest.
