GlowTub Underwater Remote Controlled LED Color Changing Light for bathtub spa by GlowTub

Edit: Now it’s several weeks later, this light still works! I adjusted my rating and adding to my review because of the amazing customer service. After writing my original review below, the company contacted me and was proactive on correcting any issues. They went above and beyond any expectations. Again, even with a little bit of rust, this light still works. 💙I received this light six days ago. I’ve used it in my hot tub twice and water has obviously gotten inside and the battery port is already rusted. I had the lid screwed on firmly.I’m going to dry it out in the sun and try a layer of Teflon tape to see if that seals it up better because this light really is cool.I added two photos of my hot tub with the light on. The blue is amazing and chill and the green makes it look really witchy!💙💚🧙The remote works only when it’s about a foot- maybe 18” or less underwater. When I had the light at the bottom of the hot tub, the remote did not work. I simply pulled up the light to make the adjustments I wanted and put the light back.If you use the suction cup, I would peel the light off by slipping a fingernail under the edge of the suction cup, rather than just pulling on the unit. The rubber casing is quite thin and I would imagine it can tear easily.

The suction doesn’t stick to east set above ground pools. It just floats to the top and goes belly up. The remote doesn’t work when it’s underwater.

Purchased two of these over the past year or so and both stopped working after a few uses. They start frantically flashing red and not responding to the remote. The only way to turn them off is to remove the batteries. Such a shame as they're really nice when they're functioning properly.

I bought this light to go with a new luxury bath "bed" mat. We're really enjoying it! It's both interesting and soothing. Everything works as expected. It's just the right brightness. I was worried the suction might give up prematurely but has not. It's still stuck right where I first put it. Not sure how long it'll last, but for now it's a lot of fun! I'll update this review if anything fails. So go for it!Update: After the first bath cycle I left the light attached to the side of the tub. When I tried it again a week or so later, it didn't work. When I opened it, I found water and corroded batteries. I was disappointed and waited another week before replacing the batteries and trying it again. It worked, but one bulb was out and the remote didn't work! I was glad at least the other bulbs worked (still pretty bright), but the light is less soothing in demo mode. After replacing the remote battery, fiddling with it, and repeating some incantations, the remote changed the light a few times and stopped again. It's likely there's an issue with the remote signal receiver in the light housing.Bottom line: For the price, this light is worth having for the fun of it. I may have under or over tightened the light before first use allowing water to seep in which could have affected the light bulb and sensor. So considering that, the fact it still mostly works, and the all around fun environment it creates, it's still worth the price. BE CAREFUL WHEN SCREWING TIGHT THE LIGHT HOUSING.

Do not leave in water they rust. I bought two of them and they both do not work. The suction cup stays on until it doesn't.
