Well the only one I have tried is the 7 function wireless remote egg and it was a waste of money. you can read about it here link It didn't have enough oomph, the wired eggs are much better and cheaper.

Out of the four you have chosen I have only tried one the 7 function wireless egg. And I found the egg to be fair, but the price of replacing the batteries is crazy. It cots around $30-$35 just to replace the batteries. Here is my review on it if you would like to check it. It's rather thorough (spelling?) Review

However with that being said I have also tried the Bliss Egg (it's not listed here, and costs more). The Bliss's vibrations are strong and can be felt very well. Also the egg it's self is rechargable so no watch batteries to replace. The battery in the remote is a small (I wanna say "N" size) battery; which costs around $5 for a pack of 2. It's also a little bigger then the 7 function egg. Over all I would recommend maybe trying to earn up some extra eden points, or see if you can catch the bliss on sale. Bc out of the two I have I am more satisfied with the Bliss over the 7 function egg.

I hope this has helped you out with making your decision. Best of luck!!
