This one flaw alone places this unit on the Z list of equipment

First unit didn't work

But when I put the battery in no power, I decided to check the battery and when i took the cover off and touched the battery it was hot, took it out, unit smelled like hot silicone (fried electronics smell) bought a power cable to try and same result

The big surprise was how quiet this little unit is, full gain no additional hiss

The unit still picked up noise with a regulated power supply

Might have been just an unlucky unit but sent it back.

Unit was defective
