Ex Input:
Bought Aug. 14th 2018. Worked just fine until Oct. 20th 2018 when it would no longer recognize my 2s LiPo batteries. Unfortunately last return date was Sept. 13th 2018. If you get this I recommend spending a few extra bucks to get the extended warranty. I'm out $50.00 + bucks and without a way to charge my 2s batteries.

Ex Output:

I read through it once to understand the message. I plan to go back through it and put it in practice. So I can't say that it worked for me yet but I can say it was an easy read and interesting.

Ex Input:
Unpacked the item. Noticed that the chromed area on the mount has imperfections. Chrome is missing/discolored to a brass and copper finish. I realize this wasn't an expensive item, but I also do not expect a flawed item that should never have made it through even a basic quality control check. Disappointed.
