ok well the station is sturdy it uses a through pass connector to the wii power cable.
the wiimotes fit in with the straps still attached which is a bonus, i'm charging two of them up now...says 5 hours charge time I will see how long they go for and report back.
You get two replacement wiimote battery covers with a ni-mh battery attached to them so you just replace your original wii cover with the new ones.
They fit very snuggly feel the same as the originals when sloted into place.
overall it seems a sturdy piece of kit...cheapest i found on the net if your in the uk is from sendit.com

cant see how it would blow my wiimotes up though!
So crank up the volume and rumble on your motes and kickback!
