Awesome product - great customer service. Save on your heating bill!

First one arrived DOA but I contacted customer service and they sent a replacement out right away. After having a few workouts with it my top line review is in….it’s worth it!

I can cut back the heater in the gym to 50 instead of 60 significantly reducing my heating costs. With a warm bar on my finger tips you can be completely comfortable at much lower temps. I only wish I had small ones for my dumbbells, kettlebells and cable handles!!!

Amazing! A game changer!

This is the best thing we have bought for our garage gym in years! My hands are always cold and grabbing a freezing barbell was the last thing I wanted to do. Our only problem is we now need another for our other bar! And please make one for pull-up bars as well! If I were to make one suggestion, it would be the timer. I would love to have a programmable timer with a clock so I could set the bar to warm up a few hours before my workout. Or even better, WiFi enabled so I can program/ turn it on from my house!

Awesome Product

Excellent product, bar is toasty hot in ambient temperatures as low as mid 20’s F so far. Also excellent customer service! Very quick response and support. I would 100% recommend this product for anyone lifting outdoors or not insulated environment suffering from an icy bar

John Harris
Exactly What I Wanted

Perfect for barbell. Love it! Can you expand your product line to fit Rogue rigs to warm my pullup bar as well? It is shorter. Also add an option to secure warmer with outside velcro for a quick wrap / quick easy on easy off, along with zipper for longer term wrap.

Thanks, John! We are glad you like your barbell warmer! And thank you for the ideas. We are always working to improve our products!

Great product

Nice to have warm barbell in cold Maine garage!
