What every best Fire Pits & Patio Heaters has:
Propane only. Users agree that the Endless Summer GAD860SP Slate and Marble Tile Gas Fire Pit (which is sold under both the UniFlame and Blue Rhino brands) is beautiful to watch, especially since the flames come on instantly and remain constant, unlike a wood fire that takes time to get going. However, they disagree about how much heat this fireplace actually produces. Some owners report it puts out "plenty of heat," while others complain they only feel warmth when right next to the fire.
A couple of quirks. Assembling the Endless Summer GAD860SP can be tricky and that's the source of the majority of negative reviews we spotted. Although some users were able to put it together on their own with no problems, others report that it's definitely a two-person job that will take at least a couple of hours, and maybe a little (or a lot) of wrangling to get everything to line up. Once assembled, the fireplace is quite easy to light and comes with handy features like a waterproof cover and a slide-out tray for the propane tank. However, we saw a handful of reports that complain the fire produces too much smoke and soot during use, as if it were burning wood rather than gas. Also, the fire pit is very heavy (140 pounds), making it hard to move once assembled.
Sturdy construction. Most users describe the Blue Rhino/UniFlame Endless Summer GAD860SP as very sturdy. In hundreds of owner-written reviews spread over sites like Amazon.com, Walmart.com and HomeDepot.com, we saw only a few reports of mechanical problems. The fireplace is backed by a one-year warranty, but we did not find any reports describing the manufacturer's customer service quality. The fireplace requires a 20-pound propane tank, so regular refueling will add to the cost of ownership.
