If that's the case, its up against the dryguys turbo.
If the microdry was just passive design, then it's about the same as the dryguys travel or similar devices.
But I really don't see how it is innovative in any way versus repackaging something 10 years old.
For all of these, the easiest method to judge how well it potentially might dry, is to just check the watts to see how much heat it really puts out and that will just be the benchmark of it's heating/drying capability. I don't believe those fin designs or case shape or positioning really going to result in any meaningful improvement versus just how many watts. I think all these passive devices are in the range of like 8-15 watts (both) to be "safe temperature".
If it's also got a fan to move air, like the dryguys turbo, that opens things up to pushing more watts of heat through. So I think fanbased dryguys turbo is around 25 watts (both), if i remember, with a couple watts to the fan. So by the watts metric this is 2x as effective as a passive device.
Then the full on snapdry/thermic active heated devices are in the order of 50-75watts and pushing heated air through (even though it's just seems like puffs); that's going to be 200% more energy then the inboot dryers.
Still this is just an easybake oven's lightbulb's worth of heat and air; compared to 800watts+ for hairdryer.
If this microdry really is pumping way more heat and air though and has watts spec behind it to prove it then I would say try it out!
