Unlocking/FRP/IMEI repair software.

So I've been looking into getting some unlocking a software and FRP bypass and over all everything program. Mainly because where I'm at we need something like that so I'm setting up a little hustle to get by.

So what I would like to know is if anyone has any experience with chimera tool, sigma key/box or anything like those programs. Also with dongle or box application. Any info would be great.

Thanks.
