Am I the only home-tester..still using the old Protime 3?Mine will be age 5 soon...3 months after my surgery..My insurance paid for it/cuvettes until I turned age 65...I was so happy with it..stiil am.. so talked to QAS and decided just to buy outright my cuvettes from them..No hassle from medicare.. I order twice a year..25 cuvettes and tenderlett's....all iI need ..since I am in range mostly everytime I test. I truly love it..recharging quickly..when the battery light comes on low......Yes, it may be heavier than the new ones..but since we don't take long trips anymore..just sits on my den desk.....First few years..had to be sure and be home..since suppilies were packed in dry ice.Last few times..they are not packed in ice..but still keep them in veggie container. Easy to get them..I let them sit out for a while before I use them.....QAS is wondeful when I call for replacements. have me on their computer. Takes all of 5 minutes to order and here when they say..like 2 days later. Bonnie
