the service was prompt and i received the items on time ... they look ok and reasonably priced ... but it's too soon for a review simply because what matters most with LIon batteries of this type is how long will they last and withstand charging and discharging under normal or hard use ... and such a thing takes at least 2 years for the average consumer to decide because, in my case for example, i have a couple of same batteries under the original Pentax brand and they have lasted for nearly a decade so far since i got them in or around 2010 and they're still going strong! now, can WASABE POWER or any other 3rd-party battery brand beat that? only time will tell ... (why did i challenge WASABI here: because another 3rd-party brand of battery i got around the same time as the Pentax ones, died a few years ago ... still good though, considering i paid less than half the price of Pentax for that one!) :-)
