So far so good, been charging at 15.5 steady and drops down to 15.2-3 when warm or under a load.

Saw no difference
Didn't really see or notice any difference in power in lights, radio, window regulator strength. I didn't measure the voltage before and after so I don't know if it really did go up but it didn't cause any issues either so I left it on. ZZP has done me good so far (no ****)

Voltage booster
It works pretty good. I'm getting a usual .5 bump most of the time but sometimes it's like it's not even there. I assume I have an alternator issue though. Definitely would buy again

Not for all Rivieras
Item probably works great. The wire connection to my alternator didn’t match the connector on the booster so I had to send it back. I have a ‘97 Riviera. Make sure to check your connections before buying.
