While this little gem may look pretty much like your typical old school buttplug, it packs a collection of features that bring it firmly into the new century.  And while many of the criticisms here are not entirely without merit, they may miss the subtlety of the design.  Regarding size it's pretty hard to generalize, as anatomy varies, as well as each b*tthole's relative comfort with friendly intrusion.  This toy varies from pinky sized at its tip to 1.5 inches at the ball, so a fair range for beginner to intermediate players I'd say.  Not to mention the use doesn't have to just revolve around cramming it all the way in to walk to the neighborhood drugstore, or whatever.  The ribs on the surface add greatly to the sensations of internal movement, along with the variety of vibrations that make gentle thrusting or rotation pretty yummy too.  Plus the knob at the terminal end makes a nice stop to thrust against, an approach which may help even the shyest little b*tthole gain confidence in how much she can happily accommodate.  Add to that a bit of hip rolling (think rumba), or swaying, or rocking and the "not very sturdy" neck works with that ball to create some delightful shimmies internally as well as right at the point of entry.  As always the admonition lubrication, lubrication, lubrication applies.So all said a pretty fun toy for some backdoor experimentation.  The vibrations are pretty decent.  Not as rumbly as some larger units but definitely noticeable and creative.  The remote clicker is a nice feature to avoid having to feel around for the button to change gears.  I especially enjoy the escalating deescalating one which reminds me of practicing musical scales but in a minor key.  Sort of ominous music for your backside.I am watching the battery closely given prior complaints, but so far so good.  Plenty of juice for playtime.  The change from blinking (charging) to solid (complete) in the on button has gotten a bit random rather recently but no indication of actual charging issues.  Will report back if it goes south.
