Has anyone tried using.....

My boss was telling me about the ad on TV recently, and I didn't know what he was talking about.
(He's a very attractive and fit 40-something)

He started to demonstrate the Shake-Weight thing to me, and I just stared at him with my mouth open - and then burst out laughing.

He blushed, and we both had a good laugh. I mean it became inappropriate, but I'll never forget the look on his face when he realized what he was seeing as he shook those imaginary weights!

My daughter bought one. Useless I think. Very awkward to use and uncomfortable too. Not worth it in my opinion.

I saw amazing results from a woman who had the DS and used P90X.

We had a 60 day fitness challenge in the new year.  There was woman who posted that she used this and really liked it.
I've been using resistance bands and doing pilates.  I have wings but they are not all shriveled up...

 
This is the best video to watch for Shake Weights!!  (NSFWish)
