Review on 🦷 Ultimate Dental Care with Waterpik Complete Care WP-900: Water Flosser and Sonic Toothbrush Combo by Jason Selby

New review: I already had two of these units and expected batteries to be available from either the manufacturer or an aftermarket source. It's useless if you can't buy replacement parts or the toothbrush is a $60 (retail) or $100 (factory) replacement. I suppose if I just buy another one I can expect to buy another one in about a year, apparently the batteries aren't getting any better. Funny thing. I had a competitor product that lasted over 10 years, used old battery technology and cost the same at the suggested retail price. The difference in battery life is in the purity of the acid used and the anodizing. The battery (see picture) also requires a soldering iron to remove and I have no idea how safe the materials are. You can definitely disassemble it, even into tips for those who want to fix it themselves, I don't know how to solder. But it's just a matter of unscrewing the bottom and then using the bottom (it has a notch for that purpose) to push her guts out from above. I think someone could make some money offering this as a service if they have ventilation equipment for the soldering work. On the other hand, I could see that it was leading to heavy metal exposure. However, the initial quality (what a bad way to rate anything) is higher as it produces more ultrasonic cleaning power, but as the battery quality slowly went down it lost that advantage over the competition for two or three months. I've come to the conclusion that the value proposition is unsustainable and am wondering if I'm just buying marketing, a brand and floss I've never used. new toothbrush, you don't have to buy that many heads :) Old review: this thing cost $70. The toothbrush battery was dead after about 1.1 years. just after the warranty expired. A new toothbrush alone costs $100. Excellent and competitive design specifications.
