With extra protection from liquid getting into the battery these sound very good, Amy. What a shame they didn't arrive until after I'd placed my order while the promo was valid!! I would definitely have purchased some. I noticed it says all of these have red LED, do these only come with red LED? I always prefer anything EXCEPT red if there is a choice.
If these sell well for you (I'm sure they will) do you plan to stock these regularly and also the manual type as well? I think maybe people will want chargers for them as well, you don't sell any suitable for these at present.
