Kestrel V2 Basic ETU : Do not recommend
TLDR: You have to buy additional tool to wire it, there's no circuit protection, the mosfet shorted and the wires caught fire.
I bought this ETU because it seemingly had the best precock programming, which readjust itself on every shot to make sure it is at the desired position by calculating the time vs the effort.
The ETU comes with a presoldered dean connector. However, the wires on the dean are soldered directly on the ETU, without connectors in between. I have a g&g cm16 and the dean does not pass through the buffertube hole. I knew this so I bought connectors and the tool to crimp them, which at this point, makes the ETU as expensive as other ones.
At this point I installed it, closed the gear box and tried it. Everything is normal. I change the selector switch and suddenly the light stops and I see smoke. I quickly remove the battery and realize that the wires are completely red hot and melted. Glad I stopped it quickly. I then realize that my fingertip and nail is charred. It dug through my nail. Luckily, it looked worst than it was. I removed the charred skin and it got only my callus.
Anyhow, for some reason, the mosfet got shorted as you can see in the picture (burnt hole in the components). I don't know why it shorted because the only thing I did was to install it with a single screw. I can totally see it as maybe my fault, but I thought that at this price, the module came with some kind of protection, but no. Nowhere in the manual it mentions that it needs a fuse, or has it. Itbis so cheap to put a fuse that I took it for granted. I am experienced with electronics and it's the first time in my life that something like that happens to me.
The thing that bugs me is : the wire that burned was the red one, which is ONLY for the microcontroller and the mosfet logic, because the ETU outputs ground, not V+.
I saw some reviews that it works good, but I'm in no way willing to take the chance of hurting myself or burning down my house for a toy.
You better buy something else.
