the more premium laifen toothbrush uses pogo pins; The one you have pictured appears to be laifen's more budget offering: https://preview.redd.it/neswy791o15g1.png?width=491&format=png&auto=webp&s=c34f678631de40a3a6511fdb8842dd9246ae262d As others have commented there are IP68 USB C ports, as literally all modern smart phones have. The problem with a toothbrush is that it's not going to be just water entering the port, it will be toothpaste and the inevitable grim that builds up (just look around your bathroom sink) that will eventually prevent the port from working properly. Modern smart phones detect moisture in the port and won't charge until it's dried out. Image how frustrating it would be to have to dry your toothbrush before being able to charge it.

If you like vibrating - Philips sonicare. If you like oscillating - oral b If you like vibrating and oscillating - laifen. I've tried all 3. I prefer laifen. I know many ppl who do not like the sensation of vibrations on teeth. If you belong to this category buy an oral b.

I really like the Laifen toothbrush. It’s made from better materials, has higher build quality and clearly a much stronger motor. And the replacement brush heads from the original manufacturer are under $5 each.

I love my Laifen brush. It’s so powerful and while I don’t feel it replaces flossing, it’s much better at covering for me when I don’t floss than either the oral b or sonicare ever was. I also think the strong vibrations on the gums is likely good for them, I have noticed improvement in the numbers for gum recession I get at my bi yearly cleanings since switching to the brush. I also love that the Laifen brush heads are sold at a much better price than the OEM brush heads from sonicare and oral b

Laifen- tried so many and love this one so much

Yeah, I had my first Laifen Toothbrush die exactly like that. It corroded and wouldn't seem to charge.
