Thanks for the add - short time lurker, first time poster.

Made my first Chinese purchase about a month ago, a P505.  I had a new to me Aspero that won't get a lot of use, the Stages that came with it was physically broken, and I rec'd a $300 allowance to replace it. I figured this would be a good venture into the budget cycling zone, and am excited to learn more from this board.

I did have two questions:

I figured a second charger to keep in my gear bag would be a good thing to have, I try to keep spares of everything I need often just in case. Given that it is proprietary, I figured proactively obtaining one would be a good idea. I emailed Magene, a month later they replied back telling me that it is $7, $20 to ship, and I also need to pay customs. Is there not an easier way to get one?

It doesn't appear to sync well on BT - only Ant +.  On BT I get a lot of drop outs, however I haven't had any issues on Ant +. When I asked Magene about it they recommended resetting it, which I haven't done yet because the instructions they provided required two chargers to do so. Any experience or feedback on this issue?
