Virtually all of the toys we currently have are battery operated which hasn't been a big problem for us, but I can definitely see the perk of a rechargeable toy. If I was in the market for getting a single high end vibe I'd definitely want it to be rechargeable, one less thing to worry about.

from what I understand about them:

the rechargeable vibes last as long as they are rechargeable - your guess about how long that will be is as good as anybody's.

the battery operated vibes last as long as the motor works. again, your guess about how long that will be is as good as anybody's.

maybe researching online about this might give you some solid info.

and as an FYI, rechargeable vibes are always more expensive, and some have a fairly comparable battery operated alternative.

I used to opt only for rechargeable toys, until I realized that, just like edeneve says, they'll be around only as long as you treat the battery well. That's related to how often you use it, how often you charge it, whether you let it sit for long periods of time 'on empty'... Especially when I accrued quite a stash of rechargeables, I realized that a lot weren't being used and I kind of wish they were battery-powered so I could avoid this problem.

I own a combination of both. There is nothing more frustrating than a rechargeable that dies at the crucial moment...then it takes hours to recharge. Batteries, you still have to stop and add more--but can get going again in just a minute or two....

I would buy which ever is best for you.

Both have pros and cons.

I prefer to buy rechargeable as I think about tossing those batteries and the effect on the land around them.

I personally prefer battery powered, I have rechargeable batteries and toys that are rechargeable are more expensive and won't last forever if you use them often.

I have a mixture but most of my toys are now rechargeable
