Perfect fit
This fit perfect in a NetGear hotspot. The factory original had began to swell and as a safety precaution I replaced the battery with this one. It’s been in only a couple weeks but it seems to hold a charge for a long time and so far it works well.

Hmmm, jury is still out on this one.
Battery works, but a super tight fit into the battery slot, which makes it impossible to remove without a leverage device (like screwdriver) and not sure the charging accurately, sometimes is plugged in for several hours with little movement in percent charged, then next thing you know the battery shows as fully charged.

Not so sure
This replacement battery is not as good as the one it replaced. Doesn’t always charge and the charge does not last as long.
