Decided to share my review of this product.
A friend told me about the gold-coated trimmers. I decided to order it although I never got their dryer (I guess it's not really matters).
First of all, it arrived pretty fast.
When I opened it, it honestly looked like a regular trimmer, the security clip was hard to open in the beginning. It's not my first round of growing weed and I did use trimmers.
So the real magic happened after a long time using - I actually noticed the difference in my hand wrist and muscles - much more convenient.
Besides that, the cut was nice and smooth, no "leftovers" on the blades - for me, that is the difference between a good and a bad trimmer.
I have been using this trimmer for a while now, and they just good as on the first day, probably will order another in my next filters order.
