Great product. Battery works as expected. Recommended seller.
Got about 30 days, as declared battery it's a super speed of light. Shipment is costly but, air transport of batteries alone is COSTY. Batteries are 100% as described, came ready to work (about 50% charge, better than fully charged). They keep voltage, included (soldered) chip for charging / discharge control works good. They are slight smaller /shorter then orginal batteries for EZBOOK 3 Pro. They need soldering (it's described before you buy). They hold charge as orginaly used batteries. Wrote about one week after installing and day-to-day use of batteries.
