Definitely works with Sprint phones. I bought two from ebay at $35 each so this Verizon deal (hopefully with fresher batteries) is a good price. Adds several mm and some weight - really can tell. When I switch back to the regular battery, the phone feels genuinely slim by comparison. Capacity wise, I get a full day with 30-40% left over. With the original battery, I would run out of juice at 4:30 or so. My wife, who uses her TP2 sparingly, gets 5 days compared to 3 with the original battery.
