I have a couple of these. Fit/finish gives a good impression. They work essentially as advertised, but be aware that the usable/recommended capacity is less than claimed due to their battery life conservation restrictions. You CAN run it to empty and fill it to 100%, but they state clearly that this will compromise battery life. OTOH, they say that you can leave them plugged-in full time which is how I'm using some of mine: as full-online no-transfer uninterruptible power supplies. They work GREAT for that. At least so far.... Note that the power supply is capable of roughly 65 watts, so your protected load has to be less than that otherwise the battery will discharge.
