I have had the frustrating experience of wanting to use a toy only to discover it needs charging. So sad! But no, I do still prefer the rechargables over regular batteries. I have a kept a few battery operated toys for those occasions, but I have found that the rechargable toys are more powerful. One battery operated toy I have is only as strong as I like the first time I use 4 new batteries. It would be wasteful in my opinion to replace the batteries with every use, so I just end up rarely using it. I'm trying to work out a routine to minimize the low/no charge situation from happening. I do think fun factory does have some very nice vibrators that take batteries and I'm sure there are some other nice brands that do as well.
Bignuf what are your favorite toys?
