Query: it's ok, could be designed better

We got this for christmas, so I can't vouch for how well the batteries hold up, but it takes some fiddling with to get the remotes charging in the base as the wrist strap blocks it from contacting the charger correctly. The directions say to keep it charging at all times when not in use, and that's what we've done. No problems thus far.
