Bought as part of upgrading my astronomy equipment to complement a cooled camera. Easy to fit but care is needed for good positioning/alignment, an extra pair of hands is a good idea.

On e of things they did to the heater that they finally made openings for the 4 screws, just in case you want ti take the top. In previous dew heaters it was just one rounded doughnut shape and thus the 4 screws were covered over whi h I understand there was a lot of complaints about this. So pleased ti see the new improved item.

Perfect fit , great delivery
👌👌

Once again very fast service
They have solved the problem with gaining access to the screws after the heater strip is installed, brilliant 🤩
Thanks everyone at flo, your service is faultless

My cooled camera has a dew heater built in, but on very humid nights it can still have an issue. Adding this has removed the issue fully. FLO delivered in double fast time as usual. Excellent service

Good for dew prevention, but…Once this heater has been fitted, it would prevent you from accessing the desiccant tablets for drying them out or replacing them. If you have reason to access the tablets and need to open the front of the camera, you will damage the heater strip and would need to replace it with a new one. Suggestion: ZWO should make it slightly smaller in order that the screws on the front of the camera are not covered by the heater.

Excellent service by FLO

I bought this tape to tidy things up rather than using a dew tape around the nosepiece of the camera , just installed yet to test my only gripe and maybe flo could get lynx Astro to make a better Y lead using silicone cable as the zwo y lead is too thick a cable cable ties are to thick , both male leads are the same size rather than offsetting the lengths just looks untidy and cumbersome , will probably lose the Y lead and use separate cables to plug into my Deepskydad Hub2 , would recommend the dew tape but the Y lead could do with a bit more thought putting into it.

Strip is easy to fit to camera I have only used it once so far and gets warm didnt get any dew
Not sure why the two spacer rings are in picture because they dont come with it but it looks like it will do the job

I bought this add-on for my ASI1600mc-cooled as I had a session that was badly affected by condensation on either the camera window or the sensor. I have fitted it according to the instructions and have had no condensation issues in the next imaging session. However, due to dust getting onto the sensor when I dried the desiccant tablets, I find it very difficult to access the camera front plate screws as they are covered in the self-adhesive anti-dew heater.
So, in conclusion, I'm sure the device works well, but could be designed to allow access to the body screws for all the intended ZWO camera models.
