Hi friends,

The Dew Heater finally comes!

Use it to prevent our camera lens from fogging up, Keep our lens dry. 


Let me introduce this heater from 3 aspects:

The material:

This Dew Heater main fabric is made of Neoprene. It's different from general cloth. 

More introduction about this fabric:

Neoprene is water-resistant, exhibits good chemical stability, and maintains flexibility when subject to a wide range of temperatures. ... Given its incredible durability, neoprene is used in the creation of laptop sleeves, orthopedic braces, swimwear, wetsuits, camera bags..etc.

After comparing it with other Dew bands, we found such material is good at keeping the heat inside, that's to say, it will be more power-efficient for us. 

The Power

High: 7.5W

Medium: 3.75W

Low: 1.85W

Compatible with most power banks, 5V.

You can power it with your general power bank with a 5V output, USB-A connector.

Dew Heater Band for astrophotography

Used it twice, with some effects.

MSM and Fuji GFX works well together.

I picked up the full MSM unit with laser and polar scope for backpacking. The last few months I have been giving it a go in preparation for backpacking season. I am impressed that it can handle a Fuji GFX100 and lens without issue, even in strong winds. I have only three very very small gripes. The padded case that comes with the Unit cannot fit all the other little bits like the laser, polar scope and mount etc. The laser should have caps to prevent accidental triggering when not in use and the little light for the polar scope can easily be turned on when not in use due to the position of the on/off button. Over all a great little unit for those tight on space.

Works well.

Longer than the one I was previously using, which lets it work with bigger lenses. The included controller is nice to be able to run it on low to stop dew and turn it up to keep frost off.

Tracker is good, laser fails when it is cold

The tracker has worked well for me (so far just with wide-ish lenses in the 28-50 mm range, I haven't tried it with anything long really), but the laser stops working whenever it is cold (below freezing) out. It'll work indoors, or if I keep it in my pocket for a while to warm it up, it'll work for a minute or so, but if I leave it installed on the tracker and let it cool off to ambient for ten minutes and then ty turn it on verify that my alignment is still correct, it won't power up.


Great product, juste what i was waiting fort

Works great

I have now taken hours of photos with the dew heater and absolutely no dew on the lens at all and it’s super easy to use and works perfect with a power bank.

Amazing little tracker and rotator

I was one of the first to order a MSM rotator from India. The first batch of rotators came with rotary switches for selecting the various options. Even during the initial stages MSM were very prompt with their service support and advice. Every time I have looked for some guidance, MSM are responsive and supportive. I have mainly used the MSM rotator as a rotator for shooting timelapses but I have used it sometimes as a travker to shoot the milkyway and deep sky objects like the Orion. The MSM rotator has performed flawlessly in every condition. Now I own two - the original one and a new version and they are both always in my bag where ever I travel. The next improvement I am looking for is longer lasting batteries although I agree 5 hour battery time is usually enough but it would be nice to use it over 2 - 3 days without having to charge it but if that means a heavier rotator then I will have to be satisfied with the present one. One of the best things about this rotator is the very handy weight !!! So if you are timelapse photographer, a milkyway chaser or a deep sky object shooter - the MSM rotator is a must have in your camera bag !!

Must have Item

If you ever experienced a well prepared trip, setup everything, ready to shoot and then the Dust is so intense, that you have to clean your Lens after every shot, you will never miss this item again. It works perfectly with a Power Bank and gives your Lens a Perfect Temperature to stay clean for a good shooting night!

Works well

Works as it should

Without a doubt it is a tool that all photographers should have in their backpack

It works very well the main reason for my purchase of the Dew Heater Band was not because of very low temperatures (-0º Celsius) but because of the condensation of humidity that I had on my lenses during some nights mainly near the Sea.
It has 3 temperature levels, which, without a doubt, whoever has to use it under harsh conditions, it will not let us down.

I recommend its acquisition for use of humidity and cold
