Have only owned the product for a month, but am completely satisfied.

Does everything I would have expected. I collect motorcycles and never remove the batteries. I'm too lazy to move a charger from bike to bike. I've plugged in most of the bikes plus a car that I seldom use in the winter and leave them on. No worries.

Only negative I've found is the leads from the charger to the battery are only 6 feet long. If you require more, you need to purchase a 25 foot extension. 31 feet is much more than I need. Wish I could purchase leads of 10 to 15 feet long.

I live on a small farm and have many pieces of equipment that have batteries. I was able to remove the batteries and place them on a work bench and charge 10 of them at one time. Plus this unit will keep them at peak level until spring arrives.

I bought one of these last year and liked it so much, I bought another.

We use these to charge batteries for clay target throwers.

Since we started using them, we do not have the low battry issues we used to have in the middle of a shoot.

The charger even rejuvinated some batteries that were questionable.

I highly recommend it!!!!!!!

This product delivers as advertsied and then more.

We have many vehicles, and products that require their batteries to be charged. We needed a product that could be left on 24/7,

not over heat nor damage / kill all types of batteries. Additonally we wanted to see status of charge. This unit fits the bill.

Plug and play. Have had many other brands prior. this unit beats them all. "Five stars"
