I love my Jingle Jugs. A neighbor gave them to me because their teenage son didn't like them (WHAAAAAAT?!). They hang proudly in the garage and anytime I need a little boost of good spirits I press the manual button located right on the front and sing along! I haven't really used the motion sensing feature or the battery power so I can't provide a reveiw on those features which is the only reason I gave it four stars instead of five. On a recent bachelor party, I brought my Jingle Jugs and whenever somone walked by they would hit the button - it was very entertaining. The "jugs" are very lifelike and look great with or without the bikini top in place. When activated they jiggle quite nicely along with the famous "T------ and Beer" jingle. Good stuff! Great for a garage, shop, or any other man-cave.
