I dunno. Five months, seven pages, and 130 posts, and so far only two people in this forum seem to have used it:
I got mine a couple weeks ago. Love it.
Definitely worth the money
The second link from a day ago consists of only those four words.
My son-in-law has the Spark and has flown it in the rain, in Iceland, but
without any additional protection. The drone completed its mission and is still alive. Thus, there is more water resistance built into these drones than I would have imagined.
This begs the question: how much additional protection is this product really providing??
To be convinced that this product works, I need to see two identical drones, one with a wetsuit and one without, flying the same mission, at 25-30 mph, of a duration over ten minutes, in a steady rain. The rain doesn't have to be a deluge, just something more than a mist. The unprotected drone has to fail, and the protected one has to return, unharmed. The test should be done by a third party, not by the vendor.
As an engineer, it seems to me that except for the battery compartment, there are a whole lot of other avenues for the moisture to penetrate that the wetsuit won't cover.
So for those reading this post, if you have this product, have you used it, did your drone survive, and is the drone still functioning the same as it did before?
