Put it to work upon receiving it. Pulse repair seems to be working with a feeble 8 year old car battery I tested it on, showing improved results. Tried it on a 12V 7.2Ah battery with 2 dead cells and it picked it up as a 24V battery, I disconnected and tossed the battery in the junk pile. It charges a healthy battery briskly enough. Charger runs quietly with the fan barely audible, selection button is sometimes a bit finicky, blue LEDs are very bright and gimmicky making mode selection in the dark difficult, though that is a minor niggle. The black parts of the casing is made of the same hard plastic the rest of the case is and not rubber as it may appear to some. Power cord length is +/- 1m, and charge cable +/- 60cm. Bang for buck purchase.

wery good
