Non-rechargeable batteries get weaker and weaker as they get used, so you have plenty of warning when it's time to change. Rechargeables stay at full strength until the charge is used up. Which means you can be going going going... right on the edge... and then...
On the other hand, I end up tossing batteries when they still have some charge, because the vibrations just aren't strong enough.
The best solution, I think, is to use rechargeables, but make sure there's always another toy within reach, in case your first one conks out on you. More toys = better!
