Smart weekly schedule 
Always come home to a comfortably warm house thanks to the handy weekly schedule. With the app you can easily raise or lower the temperature per room. You can also apply these settings for several days at once. Are you going away temporarily? Then set the thermostat knob to ‘away’ mode to keep the temperature down and ignore all schedules 

Ideal for district or block heating 
Does your home or office use district or block heating? With these smart radiator knobs, you can easily set the temperature without having to manually open and close the knobs. The smart radiator knobs are also handy in combination with your own central heating with the (smart) thermostat so you can adjust the temperature per room.  

Open window detection 
The radiator knob automatically detects if the temperature suddenly drops rapidly due to an open window or door, and will then temporarily stop heating so as to avoid wasting energy. You can activate this function for free in the app, and thereby automatically save money on your heating costs. 

Insight into your consumption 
In the app, you can see the set and actual temperature in your home in a clear graph. This graph also shows how many minutes the heating has been on per hour. This allows you to know exactly when you are heating unnecessarily and how much you could save by turning down the temperature. You can also see per day, week, and month how often the heating has been on in total, giving you direct insight into the total consumption of your heating.  

Long battery life 
Thanks to Bluetooth Low Energy technology, the two included AA batteries last up to one and a half years. Because the radiator buttons are connected to the internet via the Hombli Bluetooth Bridge, you can control them anywhere and anytime via the Hombli app.  

Control everything in one handy app 
All Hombli devices can be added in one handy app, allowing them to work together smartly. For example, automatically turn down the heating, turn off Hombli smart lights, and turn on the Hombli Indoor and Outdoor security camera the moment you leave your home using a Geofencing scenario. Alternatively, place contact sensors on a window or door and set the heating to turn off automatically when they are opened.  

Controlling all radiators simultaneously  
Do you have several radiators in a room? Then you can easily link all the smart radiator thermostats together in the app. After linking, the settings will automatically change on all linked radiator thermostats. So, if you increase the temperature on one radiator knob by turning the knob, the temperature will be adjusted on all linked knobs. 

"Hey Google, lower the temperature in the living room" 
This smart radiator thermostat works seamlessly with Amazon Alexa, Google Assistant, and Siri Shortcuts for hands-free voice control. Use your voice to turn off the heating when you go to bed early and effortlessly save energy by heating your home for a shorter period. 

Modern and robust design 
The Hombli Smart Radiator Thermostat has a modern and compact design, so it fits into any interior, even if space is tight. The housing has a metal mounting ring for extra-strong installation. You can control the temperature via the app, or by turning the knob on the radiator thermostat. The clear display shows the temperature after you change it or after you press the button  

Easy installation 
Replace any thermostatic radiator knob in no time with the Hombli Smart Radiator Thermostat. Simply unscrew the fixing of your current thermostat knob and affix the Hombli smart Radiator knob. Additional adapters for Danfoss, Caleffi, and Giacomini valves are included which are compatible with most radiator types. Check if your radiator is suitable via: hombli.com/adapter  

Protect radiators against limescale 
If the radiator is left off for a long time, scale and limescale can build up on the inside of the pipes and inside the radiator. This causes the radiator to become less efficient over time. The Smart Radiator has a built-in function to prevent this. It automatically opens the tap for 30 seconds every two weeks. This ensures that during summer that the radiator is still working to ensure optimal usage once winter arrives.

Bad Product
Size: 20oz
There was no pressure in the can. It would not even inflate a bicycle tire. Be careful there is no amazon refund or return with this item!

IT WORKS, IT REALLY WORKS!
Size: 16oz, Size: 16oz
I carry a tire plug kit in my van. Low pressure light came on and quickly made my way to air pump. Checked out tire and was at least a 5/16" bolt right between tread, very easy to locate (hissing). Inflated tire, prepared plug, pulled out bolt, inserted plug done. Almost home light came on again. Used water soap and plug was still leaking. Tried double plug and still leaking, but would take days to trigger low pressure light. Tire still had decent tread and didn't have facilities to patch, so got a can of fix a flat. I have never believed in this stuff, but it worked. No low pressure warnings for about a month. Around here they would charge $50 for a patch, 2 .25 cent soft rubber plugs and fix a flat, problem resolved!

Buy it! Lifesaver!
Size: 16oz
Yes, buy it when you don't have a spare tire because you will need it! I live in Florida and flat tires are just part of living here! Saved my life twice already and is absolutely self explaining! Cheaper then a spare tire, lighter than one too! Just throw it in your trunk and best case you will never need it but just in case!

Difficult to use and eventually hose end broke
Size: 24oz, Size: 24oz
I purchased this can of Fix-A-Flat to fix, what I believe, is a rim leak on my truck tire which needs to be filled once every week or so. When I attempted to use the product I let some air out of the tire (down to 25 psi) so it would be easier to dispense the contents. The instructions on the can say to have the valve on the tire at the 6 o'clock...which I did as well. When I attempted to make the connection using the swivel connector on the can's hose it was difficult. The hose on the can is very short and stiff and because it came coiled in the can's lid, did not want to straighten out making connecting it to the tire a very awkward process. It was hard to screw the hose end on the valve without it binding so it felt like it was cross-threading. I have machined aluminum valve caps and they go one very easily so I know the threads on the tire's valve stem are clean. I finally did get it on and when I attempted to dispense the contents it filled the hose but that was about it. I could not see any contents flowing thru the hose at all. I assumed it was not on far enough so I took it off to try again and the contents sprayed everywhere showing it was indeed under pressure....just not going into the tire. After multiple tries the hose end eventually just broke off and stayed on the tire's valve stem. I was able to get it off, but at this point the can is useless to me. Obviously I cannot and will not recommend this product. I have used this product before and had success, but that was when the hose was longer and wired to the side of the can making it much easier to use, versus how they are shipped now. I would recommend going with another product or possible going to a box store (which is what I plan to do) to find one that does not have this design. At the very least, if you do choose to disregard this review, I would try it with the tire's valve stem at the 3 or 9 o'clock position which might make it easier to thread the hose end on to the valve stem,. Also, if you choose to go this route you might just be throwing your money away. I attempted to get a refund from Amazon and was directed to the manufacture's web site. From there you are directed to use the 800 number of leave a general message that is in no way connected to your Amazon purchase. Past experience tells me it will not be an easy process so it looks like I am out the $12.
