I am restoring an old brass cashregister with very ornamental parts the pulsing isbery strong for my purposeI got this on sale for 1/2 price, so it was extremely cost effective and came with four heads...The battery life is phenomenal. It says a month, but it's been longer and I generally brush for 4 minutes 2x a day.I wish it came with some kind of travel case. But I pop the head off and put it in a baggy and off I go. Luckily I only travel about once a month.The dentist always complains I brush too hard, so this is nice. My teeth feel nice and clean, and hopefully my gums will stay attached longer.I just went to the hygienist after using this for about 2 weeks. She said it was doing an excellent job and that I’m getting in place that I miss a lot. Love that it is rechargeable.Product looks fine, feels powerful and with many different settings. However, it is very light and even the rod connected to the brush head is made of plastic. The charging port is awkward and the piece of plastic cover to protect the port is very questionable. Biggest issue is that the brush head, although looks similar to other sonic toothbrush, is not standard and not sure where to find replacement.Does it’s job & came with lots of replacement heads!
