Underwater Remote Controlled LED Color Changing Light for Bathtub or spa - Battery Operated - Size 2.75 in.

Not all the buttons work but cheap entertainment for a child (or adult).

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.

This light broke pretty much immediately and so far it's only been used twice. It technically still functions but the remote only works about 10% of the time and it's unclear what the problem is. At first, I thought it might not work when the light is submerged in the water but it occasionally will work when it's underwater and sometimes it'll randomly stop working before I ever fill up the tub and the light is still totally dry. The light itself will randomly start rapidly cycling through different colors which is super annoying and several times it's turned on completely by itself and started doing this and the remote won't work to turn it off so we've had to completely disassemble the light and take out the batteries (which really sucks when it's woken you up at 2am to begin with). Every time it's been used I've made sure to take the entire thing apart so the batteries and everything get a chance to dry out but this seemingly hasn't helped at all. Unfortunately, I purchased this as a birthday present for my partner's birthday and it wasn't gifted or used until after the return window so I'm hoping the seller will do something to mend this.

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.

Works but battery compartment does not have a good water seal

This light is perfect for the hot tub. The remote is easy to use and has many colors to choose from. Aqua is my favorite. The remote is small and very functional. The light is solid and the light it puts out is plenty of ambient light for the small tub. The suction is ok. It would work great on a solid surface. In the inflatable sides of the hot tub, it sticks ok but does sometimes come loose. All in all, a great little light for the price.

Works great!! My husband thought I bought it for the kid but really it was all for me to make my bubble baths even more special.

This GlowTub underwater LED light was a super fun addition to bath time for my kids. When it’s fully submerged, it lights up the entire tub and creates a really cool effect that little ones love. That said, the batteries didn’t last very long, and you have to be extremely careful about water getting inside the battery compartment. There is a silicone cover meant to help keep water out, but it didn’t feel fully watertight. After each use, it required extra effort to dry and clean to make sure water wasn’t sitting inside. It’s a really fun concept and works well while it’s functioning, but it didn’t feel high quality enough for repeated use. Because of that, I don’t think I would purchase it again.

Not working

We bought the light to use in the hot tub. It is surprisingly bright, and the kids love to play around with the colors. The suction cup (which attaches to the green rubber case) works well. We hope it lasts a while.

Really works well and the remote actually works the light while the light is submerged . Good strong light with lots of features so a good addition too a spa, small pool or hot tub. Like the fact it’s on a sucker and has several colour options

Please don’t buy this. Despite using absolutely properly the light is not waterproof, it is damaged after a few days and looks like this - see pics. Very disappointed and even paid this horrendous overpriced cost for it. It even doesn’t stick to the hot tub walls or floor or anything permanently and is an absolute failure . Don’t go there . What a rip off for nothing but annoyance and nuisance .
