dsmiller.com "hi-capacity" batteries?

Does anyone have any experience buying from dsmiller.com? They are advertising generic batteries for my camcorder and I wonder if they are a reputable company.

DS Miller is a great company. I have purchased several batteries from them. Delivery is very fast and the prices can't be beat.

dsmiller offers hi-capacity brand. i bought from them in the past. the pricing is OK. they offer same products as ebatts.com, batteryvalues.com. last time,i purchased from allaboutbattery.com instead since they offer same products but lower price.

hope this helps.
