Vitagoods Scalp massager - Black

Of course, it never says waterproof anywhere on the product description or documents. I read all the negative reviews about water leaking into the battery chamber so I was prepared. Still couldn't find another vibrating scalp massager (or didn't want to invest the time into researching others) so I just said I'd be careful with it, and I am. And that's how you need to use this product, unfortunately. Very carefully. You have to keep it out of the water stream and you have to probably remove the bottom part and wipe water away every time or every other time you use it. This will keep it pristine but it's definitely kind of annoying. I don't understand why in the world you'd make a product that clearly would be used in the shower and at the very least, needs a quick rinsing after use to remove shampoo and conditioner residue...NOT WATERPROOF. They put a little like, gasket sealer on the inside of the battery chamber but it doesn't do much at all. As mentioned, I'm very ginger with this and normally I remove the whole bottom part and wash/rinse that, keeping the battery unit untouched. I wipe the outside with a damp paper towel or cloth if there's residue on it. One day, to experiment, I did a very quick gentle rinse of the unit without removing the bottom part. Like maybe 3-4 seconds. Shook excess water off. Afterwards, checked the unit and battery chamber and yes, water had gotten in even from that quick rinse. In EVERY other aspect this thing is frickin' GREAT, five stars. But there has got to be a better way, maybe a gasket seal where the bottom part screws into the battery unit? Or, maybe if screwing it in just kept water out like, you know, how bottles and jars work. Or maybe an extra layer of something over the battery chamber access in between the bottom part and the battery unit to make it even just a smidge more water resistant at the very least. I'm tempted to find a thin gasket seal for glass jars and see if it can fit in there and still close. Anyway, I don't understand why this wasn't considered in the design. It kinda blows my mind. This is still a fairly good product in all other ways, but if you're going to use it, commit to being careful with it and taking it apart, wiping it, and/or checking the battery unit almost every single time you use it. Otherwise it WILL look like the rest of these negative review photos of nasty rusted battery chambers. I do know they have a new updated design, but I think it might also still have a rusty battery chamber photo gallery. Do check before you get this older model, maybe the newer one is much more water resistant or even waterproof?
