- battery compartment requires screwdriver to open for 2 button batteries (included) instead of more common AA or AAA - it connects to an a/c plug, does it really need batteries at all? - instructions are awkward, a little hard to follow - when moving it between devices to measure, the only way to reset the time & power counters to 0 for a new session is a tiny Reset button which also resets the cost back to $1.00 per KWh. It's fairly fiddly to set it back again to $0.29 or whatever your cost is. - cost per KWh is constant, so estimated usage cost is less accurate if your electric costs vary by "time-of-day" - you may need a (fairly hefty) extension cord so you can see the display conveniently + clear, easy to see & read display + pretty good product for the price

The unit is not of bad quality, but the instructions don't match the unit. You are suppose to be able to set the time on the unit but I cant get it to do any thing in the time window and the instructions aren't any help because the pictures don't match the unit. any thing I try to do is just guessing because instructions don't match the operation of the unit.

This product has extreme utility. The instructions are clear. My electric rate is 0.0799. I have it set for .08. I tested one heater on high and low getting 1000 watts and 1300 watts. I have other heaters I have to test. I have been tripping a breaker recently. I have a new Honeywell Heat Genius heater with six settings and with no indication in the manual regarding how many watts they are. This product has my genuine endorsement.
