Review: Good purchase - Good quality works well
Review: Good product, keep an eye on temperatures if not using regulator - I used this product to warm up the sides of an acrylic fish tank to stop condensation from forming and leading to mold. It worked great with the included temperature regulator, but the regulator automatically shuts it off after a certain period of time. I wanted it on constantly, so I plugged it in directly without the regulator. I got a little bit of deformed plastic on the fish tank after leaving it running it constantly for about 3 days. So, I guess I should have kept using the regulator! I'm leaving 5 stars because the quality was very solid and it looks like it would work great for its intended use on cameras. I also loved the velcro system, I was able to attach the lens warmer to something bigger than intended simply by buying a normal strip of velcro. I also liked that the regulator was a separate piece, gives more flexibility for use.

### ⭐⭐⭐⭐⭐ It works with my USB powerpack
*by B***V on December 28, 2020*

I needed an eyepiece heater to combat the inevitable breathing induced fog that cursed my infrequent viewing nights...I am primarily a visual observer, and I have a few 2" eyepieces that plop into my dob for orgasmic stellar and planetary observations. Recently with the conjunction of Saturn and Jupiter, my target was way low on my horizon and was only getting worse as the days ticked off to the 21st...was out with my wife in early December and we kept breathing on the eyepiece and it was super frustrating, so I researched and bought this thingy. It works well and plugs right into my USB powerpack that I've had for years. This one worked, while another type of heater meant for a more expensive battery setup did not work with my powerpack and an adaptor cord to USB (returning the other one, cause it was just an experiment to see if it would work and it did not warm appreciably). I don't need a dew-not or dewzapper system, when I have something that works very well with my USB pack...you mileage may vary, especially if you intend to use a 12v power supply for other things and justify a $150 power distro system.
