Had acquired 5000 3 years ago in the package with two handsets, the Triumph. After 11 months, the battery was in both handsets over, the equipment has been replaced on the supplier. After a further 11 months the same game again two new handsets. This time, with the indication that the guarantee would still expire in another 2 months. Now we have another 15 months, and the problem with the battery pack is back. Invite all tips as the battery only after complete discharge again or never leave the brush head when not in use on the handset (water from the brush could penetrate into the handset) were observed. I can only advise all interested parties the Triumph to buy. Dressing super but a very short time. For me, this is part of the product policy of the company. Braun / Oral B and is by design. I will not purchase products of this company more.
