WHEN THE POPULARITY OF THE SPRINT BOOSTER TOOK OFF LAST YEAR I DECIDED ON MY TRIP TO GREECE TO VISIT BOULEKOS DYNAMICS IN ATHENS. I VISITED THEIR REALLY GREAT SHOP AND PURCHASED A SPRINT BOOSTER. THEY ARE EXTREMELY HELPFUL AND IT WILL NOT DISSAPOINT. THE ONLY DOWN SIDE WAS THAT IT COST ME 50 EUROS FOR A DRIVER TO TAKE ME THERE FROM MY HOTEL IN THE OLD CIY/PLACA AREA OF ATHENS.
