First of all, a high quality 24V air-cooled charger like this is approx $132+ without S&H. I have Schumacher Chargers and they all operate very well for the price. The weak point on these chargers is "whimpie" wiring that is usually the cause of problems or alleged failures of the unit. If you are not "technically inclined" and have problems, ask a friend or acquaintance who can check the unit. The most common flaw, in my experience, is the connection near the alligator clips, since this area gets the most movement. A continuity check of the wiring can usually locate the fault. Also, since this unit does not have an on/off switch, I simply plug it into a power strip equipped with an on/off switch. A simple fix can save unnecessary replacement of a good unit. In my experience, Schumacher provides a cost effective product considering the price and the service.

It works as advertised. Would be more convenient to use if it had an ON-OFF switch. As it is, On and Off are accomplished by plugging it in and unplugging it.

I have only used this charger a couple of times but so far, so good. I like the fact that you can set it on automatic and forget about it. I would have given it 5 stars if there was an off switch. Would be nicer than having to unplug it, which in time will probably damage the cord. Also, after I purchased it, a mechanical engineer told me that my batteries would last longer and would both get an equal charge by charging them on the 12 volt mode sepeately rather than connecting the charger in series to both batteries and charging them on the 24 volt setting. If that is true, I didn't need a 24 volt charger because I couldn't find a 24 volt baffery, only 2 12 volt batteries connected in series. I still like the unit, thus far.
