41 customers mention "Noise"16 positive25 negative

Customers are mixed about the noise. Some mention it's quiet, they like the white noise effect, and the lowest setting is much quieter. The pump is audible but just like background white noise. The silent mode is good. However, some customers say the first had a very high pitched noise when the pump turns on that was hard on. It sounds like a jet taking off. The last 2 years due to the pump eventually producing a loud whine.

"...The lowest setting is much quieter...." Read more

"...If I have to go to the high setting, the noise will disturb my husband. I will be heartbroken if the Ooler keeps going in the direction it’s headed...." Read more

"...We like the white noise effect! On the quietest mode it really is almost silent, but we use Regular...." Read more

48 customers mention "Performance"0 positive48 negative

It also spilled a lot of water getting it filled the first time. Some say that it leaks almost a half cup of water per night and leaves a wet spot on sheets and mattress.

"...The pad is also reportedly more prone to leaks...." Read more

"...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...." Read more

"...The bigger issue is the mattress pad sprung a leak at the connection point to the cooling unit...." Read more

"...Just after the warranty expired I kept experiencing leaks from one of the hose sets...." Read more

29 customers mention "Durability"5 positive24 negative

"...I disassembled it to find the tubing was cracked all throughout as if dry-rotted...." Read more

Hose leak after warranty period
1 Star
Hose leak after warranty period
We were satisfied with our purchase until it sprung a leak 6 months after the two year warranty period ended. Fortunately we caught it early enough before serious water damage occurred. We were told by Customer Service that the pad + hose unit could not be repaired, and that we would have to pay $350 for a new one - minus a 25% discount. Yikes! Apparently newer models come with a fully detachable hose, but ours has the hose integrated with the pad. I found the source of the leak (see photo) in a place where the hose was bent as it went from under the bed to the control unit. A bad design in my opinion - the hose is WAY too long - with no instructions about being careful about any hose kinks. I’m very disappointed and undecided whether I will buy a new pad, but suggest that existing owners make sure there are no sharp turns in their hose to help avoid this issue.

I've had one of these for a bit over 4 years and it has worked well. The app and Bluetooth connection work well. The reservoir sells well and I only need to add water once or twice a month. I usually run it on the middle setting and while the sound is noticeable it is white noise and doesn't affect my sleep. The lowest setting is much quieter. I have it set to cool to 60 degrees and come on automatically about 15 minutes before I typically head to bed and the bed is always cool by the time I climb in. It then warms a couple of hours before I wake up.

I haven't tried the Dock Pro so I can't compare. But it costs a few hundred dollars more, has a reportedly finicky WiFi connection, and the reservoir needs frequent refilling. The pad is also reportedly more prone to leaks. And the Eight Sleep system is much more expensive and requires a subscription for the first year.

So given my experience and the alternatives, and the fact that this model is being discontinued, I just purchased another, for backup, at the $599 sale price.

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!

I know you. You’re taking timed-release melatonin, and have a regular sleep schedule, and are doing everything to maintain good sleep hygiene—and still you wake in the middle of the night. You’re hot. Or cold. Or you need to pee. But most of all, you can’t get back to sleep. So now you’re cranky because … you’re doing all of this, and you still struggle to get the full complement of sleep you need.

Meanwhile, you’ve heard of this ChiliSleep thing, but holy crap! That’s a lot of money for what is essentially an oversized heating pad … that also cools. (Well, okay, that’s different, but does that justify the expense?)

I know you because that’s where I was a few months ago. Looking, wondering, hopeful but put off by the cost. My sleep had improved dramatically with the practices I’d put in place to reverse all the damage done by anxiety and workplace stress. But I thought things could still be better. I used to be pretty good at this sleep thing. I wanted that again, after 4+ years of increasing struggles. But $799? Holy cow.

ChiliSleep apparently gets it, so they have a brilliant marketing strategy. They let you try before you buy: a 90-day in-home trial. If you don’t like the product by then, send it back. Know why they do that? Because they know that, after you have this sleep tech for, oh, say, a couple of days, your attitude shifts from “Okay, so I’m just trying this out, and I probably won’t keep it but I’d like to know if managing the bed temperature offers any benefit at all …” to a firm “Okay, Kyro, Inc. (the firm that makes ChiliSleep), you think you’re getting this OOLER back? You can come pry it out of my cold, dead hands—because that’s the only way I’m giving it up.”

It’s surprising how little time it takes to make this transition.

I love mine. In cool winter months, I program the tech to warm my bed before I get into it, meaning I don’t load up on warm jammies and thick socks, only to wake at 4 am sweating. I get the bed comfy enough to foster sleep, then program it to drop to a cooler temp later in the night, and warm up again in the morning to wake me. In the summer, I want the bed to be nice and cool when I hop in after a sweltering day, so I program the temp to drop, then raise after I am asleep and the ambient temperature of the house cools down. That way I don’t wake up in the middle of the night shivering.

And how am I sleeping? Like the dead. Seven-and-half or eight hours every night. All the way through the night. (Oh, yeah!) Great dreams. Then waking gently as the bed warms, ready to face the world with energy and focus.

So, I kind of think the $799 might actually be a bargain.
