I love rechargeable batteries. Just about every battery-operated gizmo I own gets rechargeables, and they do just fine. The only time I've ever had problems with my rechargeable batteries is in sex toys. I automatically reach for the rechargeable batteries when I reach for a toy, but I've noticed that many toys are simply less powerful this way, even with freshly charged batteries.
I want to use only rechargeable batteries in everything, but I just almost wrote a rather unhappy review of a toy because it was so weak... until I put in old fashioned energizers.
Have you had issues with this in the past? And have you been able to find a brand of rechargeable batteries that are consistently as strong as disposable batteries?
