Exclamation ESS DirectFlash unit VS. Active Autowerke SIMON

I came across these two handheld devices you can bump your HP.

Active Autowerke clearly seems to give more hp (86 Rear Wheel HP and 117 Ft lbs) compared to ESS's (40-50whp range).

Whats your thoughts on these guys?
Is it safe to increase the power so much without reinforcing transmission?
Which one seems more reliable?

I recently read about the blown out rear axle of an X5M which had installed ESS
