FastRackBrew Fermentation Heating Belt, 1-Count, Blue, Large

Heats well. Very hands-off. I didn't have any issues with it turning off or overheating.

Works great for keeping printer resin warm in the winter. I didn't want to stop printing during the winter when it gets below zero where I live. Purchased this over a expensive printer heater and worked wonders. Wrapped it around the vat and attached clips. Works greatThere are stl files you can print that will clip this snug to your vat. Just look them up online. Along with great youtube tutorials for using one to heat your 3d resin

Works pretty well for my carboys. When looking for a heater for a fermentor I was looking for one that would work best for the variety of fermentors that I have (Buckets, Big Mouth Bubbler 6.5 gal, and Speidel 30L). Being that my fermentors vary in size and shape, I thought the belt \would work better than the wrap around heaters. Since I didn't go with the wrap around option I can't really compare the two, but am pleased with how the belt has worked out for me so far.Only complaint would be that the one I received does not work/look like the one pictured. Mine is a little more turquoise in color and has a plastic flip switch clamp lock on it which required you to overlap the belt through the clamp in order to adjust the size. This works fine, but I'm a little concerned about hot spots as well as belt wearing where the belt overlaps. Once the belt heats up, it tends to slack as well so I probably wouldn't recommend this on a standard bucket unless you add additional securing to prevent the belt from slipping once it starts to slack. I've only used it on my Big Mouth Bubbler (6.5 gal) and my 30L Speidel, both of which have ribs on them so I can tighten the belt just above a rib line without worrying of it slacking enough to slip off.I use this along with an Inkbird Itc-310T temperature controller and have had good results thus far. I would recommend applying the belt when your liquid is fairly close to the temperature range you want as the belt works best for maintaining temperatures much more so than overall heating. My first time use took approximately 10hrs to raise my temp 4 degrees from 70 up to 74 in my basement with an ambient temp of about 66 degrees. Once the temperature range on my controller was met however, it worked very well at keeping it within the set range.The only down side I have with the belt is that there is wasted/lost heating from the end of the belt to the fermentor past the point of the clamp. Unless your fermentor has straps you can slip the belt through to keep it into contact, the end of the belt just kind of hangs in the air

I use this with my conical brewer for making Mead and it heats it slightly and made it ferment much faster.

I now own three of these heaters. They help me make beer and wine during the months when the air temperature is too low up enable yeast to finish their job. Yeast go dormant before they eat the last bit of sugar in the brew. Then, after bottling, they resume eating after weather gets warmer. And, bang, the wine bottles blow their corks or the beer is too fizzy. I have another heating belt from a different manufacturer, with a rheostat to regulate levels of heat. But it doesn’t work right. This simpler on/off control is better. Just unplug it when the brew seems too warm, and then replug later when fermentation slows too much. When it is on and you see no evidence of fermentation, you know you can bottle safely.

This brew belt does a great job on keeping my resin warm for 3D prints.

Much cheaper and more effective than elegoo heater I was using in my Saturn 4. Fits perfectly without interfering with the tilting vat.

For those wondering if it works with an Elegoo Mars 4; it does not for direct vat heating, it rests on the z axis causing failed printing.
