Works as expected, keeps dew from forming on lens.

Poor quality switch. It lasted less than three months. That's about 10 days of total use given how much rain we've had, which amounts to turning it on and off about 20 times. Then the switch failed. Replacing with a trusted name brand.

The 3 settings are great when running on batteries, you can use as little power as needed to increase battery life.

comme je disais fonctionne bien je l'ai donné un cadeau mais je n'ai pas pu essayer la durabilité du produit

alright, this is used for 2 inch eye pieces on a telescope and my canon lenses. For anyone who has used the telescopes at night, or done photography in cold weather, you know that foggy or misty lense.......drives you to drink!! This will be a bit big for the smaller eye pieces, but the 2 incher's are just fine. For 90% of standard lenses you will be good also. For me, the usb power supply meshes very well with the adapter I have that turns my Dewalt 20v batteries, into power sources for these warmers. And they work!!! If they can handle the Michigan Winters, they should be able to handle most of what can be thrown at them. Power draw is moderate, allowing me to power 2 of these, from a 5h battery, for several nights, viewing 3-5 hours per night. For me, this is a no-brainer
