Fortunately, I use it only as a secondary back ...
on 8 February 2015
I am only giving it two stars as it does not fit at all well into the slot in the back of the GPS. After a bit of a fiddle it will 'click' into place but that can be misleading as it will 'unclip' when handling the unit causing the GPS to switch off. I have had to use tape to secure it but it's not a 100% solution. Fortunately, I use it only as a secondary back up to the back up GPS if you see what I mean (there are a total of 4 GPS units in the aircraft); I only use mainly for flight planning and to make a track log of the flight as the primary GPS (Garmin GNS 530) does not have that latter feature. Battery capacity seems good. I was not prepared to pay for a Garmin battery, so if this cheap alternative had not been available I would have withdrawn the GPS from use. Therefore, it represented good value for money for me. If the battery had fitted like a Garmin battery I would have given it 5 stars.
