Edit 2* I reached out to the customer service team since there is supposed to be a warranty. They replaced the old one completely free of charge. So I feel very confident in this product due to how well they took care of this situation.Edit* I had to go from the lowest setting to the highest over time as it was not keeping cool like it did when it was new. Now even the coldest setting 9 months later is barely cool at all.So far I have had this for 3 weeks and it has been a game changer. You have 4 different settings for temperature and you can adjust accordingly. Just keep in mind that you do need to keep the container that holds the water higher than the mattress.If I had to nit pick, I would say that I don't really like having to refill it every other day. I also wish it had different size pad options to match your bed better. But I have never slept better than I have since I got this.I have an issue sleeping really hot. It's almost like my core temperature doesn't cool down when I try to sleep if I had to guess anecdotally. This cools my core for me and I sleep really well most nights now. At least by comparison to how I was before.For the cost, if it only lasted a year I would buy another one.

Its best for cooling your bed and its very silent

I've been using this for a few months now, and I love it! As per the headline, it's simple and effective. As it works on evaporative cooling, the temperature it cools to depends heavily on the ambient temperature and humidity though, hence the mixed reviews in this regard.How it works (for those inclined), is just a tank of water, a pump and a fan. The pump pulls water from the tank at the bottom of the base station, pushes it through the tube that runs into the sheet, splits into multiple pipes in the sheet and back out of the sheet through the return pipe back into the top of the base. The water flows down over a paper-like filter, which has a fan in front of it. A small amount of this water evaporates which cools the water as it flows over the filter and back down into the tank, to be circulated around again. The controls allow you to adjust the speed of the fan, and how often the fan turns on/off. That's all it really is.But there are downsides (in no particular order):1. You have to top up the water before bed. - No hardship.2. It needs cleaning regularly, which can be arduous. This can be reduced by dropping some chlorine granules (hot tub supplies) in with the freshwater. Note: Don't use bleach or anything, it will bubble up inside the machine causing all of the water to slowly leak out overnight as the bubbles burst outside of the tank and run down the insides of the base. Ask me how I know!3. The fan inside is not *loud* at all but it *could* be quieter. When it fails, I'll probably replace it with a Noctua fan.4. The vibrations from the pump can flow through the pipes and into the mattress, causing a humming sound to reverberate through the bed, which you can only hear when you put your head on the pillow. I resolved this by making sure the inlet/outlet pipes don't touch the side of the mattress where the mattress is unpadded (where the springs are).5. Would be nice if the pipes were a little longer. Could add a coupling and extend the pipes I guess.6. You can feel the smaller pipes within the cooled sheet itself, they are soft and this does not bother me. With the exception that over time with use, the layout of the pipes inside the sheet can get a bit messed up and start crossing over each other causing lumps where they cross, which requires some finagling to resolve and get them sorted out.7. It should really be kept higher than the bed.8. There is no 'temperature sensing'. Ideally, you want to be much cooler at the start of the night, (the body temperature drop helps you to get to sleep more quickly), but then not so cool later in the night. There's no support for this, so it's possible to wake up in the night/early morning too cold! Also, the room might heat up overnight if your door and windows are closed, so you could wake up too warm because you went to sleep on a low setting. I might resolve this one day by hooking the fan and/or pump up to a raspberrypi, with a temperature sensor in the water but for now, it really isn't a big issue.9. The buttons are on the top... but the machine *should* be above the mattress... so you can't see what you're pressing without getting up - Annoying. There is a remote, I've never used it though so I can't attest to its usefulness or complain too much. The raspberrypi solution would resolve this issue.10. Mine came with a US standard plug. So I needed to buy an adapter.These all probably seem like they amount to a lot of bad things to have to put up with, but honestly, the only reasons this didn't get 5* is the lack of a temperature sensor and the cleaning routine.I use this every night and for the price, it's an absolute dream. The cost and simplicity of repair make it well worth it over other solutions such as paying for an 8Sleep subscription. or having your bed sheet moving about with those that blow air through the sheet.

It uses about 1/2 gallon of water each night but I no longer sweat under the covers. Follow the care instructions, it well worth the time. I maintain my home warmer than I would like for my elderly mother. Now I don't have to use a window unit in my master bedroom! WooHoo!!

This thing works so well. I live in El Paso Texaswhere it is a hundred plus every single day it is so hot at night and I'm a big guy and I can't sleep because I'm so hot just covered in sweat I purchased this thing the very first night was so good I slept so well I did not get hot at all. The only thing I can say bad is that the hoses are very short it would help if they would add about another foot to 2 ft to the hoses that's it easy to set up nothing to it.
