    It's OK

    Overall: 4 out of 5

    I purchased this because my wife (who uses a lot of batteries in her cd player) kept complaining about battery life. Her player would stop working. She would bring me the batteries to check with my VOM. I would pronounce them 'DEAD'. They were put in the recycle bin. This way, she checks them and tosses them herself. Got me out of the loop.

    just got from backorder, I like the 29-1050 more

    Overall: 3 out of 5

    This is a good tester, but you need a battery (1-AAA) for power, whereas the 29-1050 doesn't need a battery to operate. Verdict: this one is good, but the 29-1050 is "not dependent" on battery power to operate and is a little less expensive.

    Disappointed. Not as accurate as Part No. 29-1050 (MW222)

    Overall: 2.5 out of 5

    I purchased this because I thought I would like the design & smaller size a bit better than Part No. 29-1050. Unfortunately, the battery test results don't agree with those from the 29-1050, which in my opinion is much more accurate. Every new alkaline battery I test (D, C, AA & AAA) only indicates 1/2 "Good" on this unit, whereas they all indicate full "Good" on the two 29-1050's I own. In addition, fully charged NIMH batteries, which indicate full "Good" on the 29-1050, only register as "Weak" on this unit (28-12547). The 29-1050 has a separate scale for rechargeable batteries, but this one doesn't (which is probably why they register as "Weak.")

    The web listing does not state whether or not this device tests batteries "under load conditions."

    My recommendation -- get the MW222 (Part # 29-1050) for more accurate battery test results, especially when testing rechargeable batteries.
