I've bought three of them -- I'm actually using DeWalt because of that. But the batteries all arrived and refused to charge. I probed them with a multimeter, and found the cell voltage was quite low. Hooking it up to a constant current lab supply for ~30 minutes raised the cell voltage enough to get the charger to accept it... but I've only had one run with them. I hope they'll work again.
I'm a heavy DeWalt user and I'm already a little salty sometimes about how much they charge for their batteries. If they change up the standard again so I need adapters or new tools, I'm going to switch manufacturers altogether. So far I like their stuff well enough, thankfully I haven't run into any problems with new batteries not working out of the box yet. Knock on wood
> always wait for a sale or deal and get the batteries free with tool
I agree. I don't think I've ever paid full price buying a battery by itself. I just can't stomach the terrible value. I watch for a sale and pick up a new tool with the battery I want. I've got a few relatively obscure tools that way that I'd probably not bother purchasing otherwise.
It's price segmentation - they know that a contractor/employee who needs a battery ASAP will pay sticker price, whereas homeowners will wait for a sale.
