Bests & Worsts Reviews from Amazon

I decided to upgrade to the P4460. This was a mistake for the following reasons: - The menu and reset buttons on my P4460 rarely worked. I had to press them a dozen+ times to get them to register once. The other buttons were more reliable, but still not 100%. That's very bad for a brand new device. - The LCD display of the P4460 was much harder to read than the P4400. - The P4460 failed to display wattage for low-wattage loads. Anything under 9 watts often showed as zero watts. That's useless for my applications. So I've returned the P4460 and migrated back to my P4400.
