The Stunner held up during the water testing just fine and the batteries lasted a lot longer than the Marvel I tested earlier in the day (I try to take a break during testing different toys so the full effects of each do not get in the way of the others).  This one was lined with a series of rings, tentatively used for additional stimulation (especially during anal play from what I was told) but Nadine quickly realized the major flaw in the design.  While having the vibrating bullet by the tip was nice initially, when the toy was deep inside of her, the vibrations were minimal even on the highest setting, the strength of the device already among the weakest we've tested together. 

So the trade off in duration was a weak vibrator that really couldn't trip her trigger, her comments that it was barely above a dildo in terms of ability a slight to the toy that it seems to have deserved.  The 2 AAA batteries were the same type and all other aspects of the testing similar too so unless you're looking for a flexible jelly-like vibrator made of TPR with the vibrating ability of a few molecules of galvanized steel, you might look this one over for something better.  Otherwise, the company described it in identical terms on the back cover and website, saying:


• 3 stimulating speeds
• Easy push-button controls
• Phthalate-free and body-safe
• Satin-Smooth coated controls
• Hygienic medical-grade TPR
• Shower & bath-friendly
• Jelly like material flexes and conforms
• Ultra-powerful motor soothes and seduces
• Maximum intensity with minimum noise

So I had no recourse but to rate this one as a Skip It for anyone but beginners or those sensitive to stronger vibrators, the basic claims accurate but not enough to merit a better rating.
