I was impressed with the speedy delivery all the way to Sweden, just 2 days after dispatch, and I opened the package, inserted the batteries and hit Start. A few seconds later I was given a powerful head massage, with guided, spoken relaxation, squeezing air bag massage and vibrating massage, music and an overall sensation of well being. Now, the air pressure massage is really powerfull (it's adjustable, don't worry) so don't let "battery operated only" lure you into thinking that this is some weak product, it packs some serious power! I can't write more now, I am off to relaxation heaven, and then I'll order some more Osim products :)
