Great Customer Service
Fast turn around. Package came with both pulleys for direct replacement of the original molded plastic GIOT pulleys. These pulleys match the Body Solid GS9 upgraded pulleys exactly.

Reliable and Durable
We finally had the heater installed yesterday. It’s exactly what we needed!! Thank you so much for all of your help. John really went above and beyond. My greenhouse is now safe and warm again for all my critters!!
Michael K
I'm Satisfied
Two weeks after receiving the AC300 and B300, we had a 7-hour power outage due to a heavy thunderstorms. The Bluetti powered our home fridge, TV, and computer without any issues. We are very thankful to have them.

Great Value for Money
The stove is working beautifully! Up here in the San Juan Mountains, we're starting to experience some chilly mornings. Today, it was below 30 degrees at 7 am! I'm grateful for having this Heater, especially since the days warm up to nearly 80 degrees, making it pretty spectacular.

Impressive Selection
I've been using my Bluetti generator for three days now and it's still going strong at 60% availability. I absolutely love it!
