Sleepme OOLER Sleep System – Cooling & Heating Mattress Topper, Automated Temperature Changes: 55-115°F (Half Queen (80" L x 30" W) Off-White

I splurged on this, hoping that I wasn't wasting my money, but I was inspired by the good reviews and thought that I would try it. For many years I've had trouble sleeping due to being hot. The only way that I could sleep well was to have my bedroom very cold. I'd be chilly going to sleep but then as my body heated up the mattress and bedding I'd warm up. (This has happened to me with several different mattresses, so it's not just that.) If the room was at all warm I'd toss and turn all night long and never get deep sleep. So in desperation I tried this. I was a little worried that it only gets ten degrees cooler than the ambient temperature, but I have discovered that's more than enough! At first I set it quite cool, because I thought that's what I needed. However I'd awaken cold, even with a thick blanket on. I kept warming it up and now I keep it at about 73-74. That seems perfect. The magical part is that because the Ooler adjusts, I no longer have the issue of my body heat heating up the mattress and bedding! As my body warms up these things, the Ooler cools down, to maintain this exact temperature. The temperature that I go to sleep at is the same one that I have all night long. Another thing that I love? It used to be that if my foot went to another part of the mattress it would be cold, back when I had to keep my room super cold. Now my entire bed is comfortable and it feels like I have a much bigger bed, just due to that! I love awakening and turning up the heat too. Yes, you can adjust it to do that automatically, but I work rotating shifts and it's just easier for me to do everything manually. I turn it up and before I know it I'm feeling toasty and ready to throw off the covers and start my day. Now I'll be the first to admit that I haven't tried this in the summer yet. I will come back and edit this review once I try it in the heat. I do use a room AC however, (which last summer wasn't cool enough for me, but I'm expecting this year it will be) so that will help matters. I am absolutely in love with my Ooler (including the white noise aspect which definitely helps with sleep) and it's one of the best purchases for my health that I've ever made. Thank you for an amazing product!!!

I've had nothing but issues in the ~16 months I've owned this.My first problem occurred 6-7 months after purchase. The base unit started heating instead of cooling (set to 70°, app reported 107°). Support was great and sent a replacement (refurbished hardware) while I returned my unit. FedEx lost the return item, but support reassured me that I would not be negatively impacted by this.My next problem occurred another 6-7 months later (I had the replacement unit for ~6 months). The main unit slowly leaked. I'm not sure how long it was actually leaking for, but it soaked / ruined the wood that it was sitting on. Support was less awesome but still acceptable, as I needed to send my unit in and wait for it to be refurbished (3 weeks).My final problem will likely be the last straw and the end of my Ooler journey unless Ooler makes an exception to their 1 year pad warranty period. I recently washed the pad (not the first time, but also not a regular occurrence since the manual states to wash 'as needed') and the pad began POURING water all over the bed and carpeted floor when I connected it up and started the system. I did not realize it immediately, but 2 tubes broke / disconnected inside the pad where they connect to the main connector. The resulting scene was a ton of fans, towels, and soaking wet bedding / mattress. My wife and I needed to sleep elsewhere in an attempt to let everything dry as best as possible, and hopefully there's no mold as a result of the ordeal.Aside from the breaks (which alone should be enough of a warning to make you steer clear), here are my technical opinions:1) setting the temperature sets the outlet temperature of the unit. The app can report the outlet temp and the return temp. I always wished this would allow you to control based on the return temp instead. The way it's setup has (had) me adjusting the temperature to get comfortable different nights. Some times the same setting was too cold, other times it was too warm due to ambient temps. The return temp seemed like a better indicator of how I was actually feeling.2) the schedule sometimes skips a step. Not sure why this would happen, but sometimes the unit would end up staying on all day unnecessarily.3) I think forced air would be a better way to go than water. Sometimes I would feel clamy due to the natural condensation that occurs when 2 different temperatures come in contact. Forced air would help dry this out, and will probably be my next attempt when it comes to trying to relate my sleep temp.4) the self cleaning option won't keep you from needing to maintain / clean the unit. Granted if the unit breaks every 6 months, you could just ship it back to be refurbished and maybe they'll clean it for you.I'm actually very disappointed that it's so unreliable. When it works it's great. I just cannot in good conscience recommend something that will inevitably ruin something you own. A leak will eventually happen. I didn't want to believe it when I overpaid for this in the first place, but I've certainly learned my lesson. It's not a matter of IF this will break, but WHEN.Just don't buy it!
