We usually have 4 to 6 chargers in use and have always been very happy with Parmak. More power for the price than many other chargers. This is the first we have bought with a digital volt meter. It usually reads 16,000+ volts during the day and 14-15,000 volts early on damp mornings. I like that you can tell with this readout if there is a major OR minor short, such as we need to clear grass out of the net fence now, and also if we can leave it a little longer. We also have several Parmak 12 volt chargers, one of which the cows rolled around in the pasture for a few years, and it still worked. Great customer service - they sent a replacement fuse holder without charge when we lost one.
