This product is intended for any battery powered toy that takes four or less AA batteries.

I know some people might be thinking, "I can get a better deal on batteries at the store; why would I pick them from Eden?" Well, let me tell you, the convenience is amazing. I wasn't a very attentive shopper and didn't realize that batteries were not included with my latest toy purchase. Luckily for me Eden recommended I purchase some with my order. If I hadn't, I would have received my toy in the mail after eagerly awaiting it, only to realize I had to wait longer until I could find batteries to put in the toy. So lets say that I didn't already have batteries in the house. If I went to the convenience store down on the corner, I would be paying $5 for a pack of four and it would have made no savings for me. So then lets assume that you are a frugal shopper, and you are going to have the make the long trip to the store to buy an expensive jumbo value pack of AA batteries, and of course since you are at the store you are going to shop for more things (even more time away from your brand spanking new toy!).

The batteries themselves are of good quality, no foreign knock-off stuff, Duracell AA batteries. And did I mention they are fresh as well ? It is currently May 2013 and these AA's don't expire until March of 2019! These certainly weren't sitting on a dusty warehouse shelf for years.

The packaging is a cardboard backing with the batteries covered by clear plastic, much like you would see on a rack in a store. The packaging just lets you know the standard stuff: that they are alkaline batteries, 1.5 volts, packaged in the USA, made by Duracell, etc. They have an easy open tab perforated in the back of the cardboard so there is no need to fiddle around with scissors or a knife to open them. Considering they are batteries, once you open them up there is no need to keep the packaging just for four batteries, so you can just discard it in the recycle bin.

I put them into my toy, and it functions great with good power. I've never experienced any bad events with these batteries, such as fires, leakage, sparks, etc. What can I say other than these batteries work great, in my personal experience?
