I got mine last week... had to send it back to AE for replacement.
Software was acting up. It would shut itself off when I want to change view screens and sometime it would lock-up and can't change any setting without unplugging the unit. and then I get this average volts reaching at higher than 60volts! and the lower half of the LCD panel would dissapear. and dingbat text would sometimes show up, and . . . .
AE costomer service was great. Just send it back and I'll get a new one. Hopefully I'll have better luck with the new one.
When it did work.. it worked great. and yes it will charge AAA nimh cells. The audible tone is way too loud. When I get it back, I'm just going to open up the case and put a piece of tape over it to tone it down. (of cource after the Warrenty expires)
I believe the Quasar Pro is made from Integy. Functions are identicle to the 16X5 that I also own. If this is the case... the optional backlit module available from the Integy website can be installed. I'm going to order one and try it. The only advantage over the 16X5 is that you can turn trickle off 0.0mv. and very compact no external power supply needed.
The Quasar Pro is probably the best charger on the market today.
It does everything.
