While the cooling efficiency is good, I was not expecting the weight and bulkiness around my neck. Within a few minutes of wearing it, I had a headache and felt like I was trapped in a device. The cooling effect is useless if it can't be comfortably worn. It may be OK for a man, but not for me, a lady. I will be returning it for the previous model.

Buyer beware. I ordered the product new and I was shipped a box that was previously ordered and the item was completely missing. Given that this is a hygiene product I find it totally unacceptable to be shipped a used product when you are expecting a new product. It’s absolutely gross.

If you're hot at a sports even after a workout. This device is very handle. This is my second device from the company and I'm enjoying this allot.

I had the first-gen product and when the next gen was released I had to try it on my trip to Asia. Major changes are flush buttons that are harder to hit accidentally and more battery capacity. The app is nice too!

Two weeks of cool weather went by until I hit Hong Kong Disneyland today. You can see the device on my neck along with the castle in the background.

The weather hit all bases today from hot and muggy to cool and raining so I carried it in my backpack a few times when I didn’t need it.

The downside still exists that you need to carry a large USB-C charging pack with you if you plan to use if for more than 3-4 hours a day.

Or you can do what I did; switch to the first generation after running out of power in the second generation. This let me charge it in my backpack.

For nearly $400, a one size fits all needs adjustable fit, logically. But is not and I need a large version. I am 6’ 180lbs, so not on XL size spectrum. It says “memory rubber” wher it bends, but it’s maybe memory unwrinkled when closed

I tried I few devices before specially Ranvoo AICE3 and lately Ranvoo Lite 2024 and they’re good AC units and I been using ranvoo AICE3 for a long time and it’s good but torras make it a big different with cyber I love this this thing looking great and comfortable and also strong wind and colder ,, great product 🙏👍

The cyber comes in a compact case, which makes traveling practical, and the quality is impressive.

I bought the cyber for my wife, who is a petite woman, and she really enjoys it. Though we have not tested in the Texas heat yet, the cold air provided by the unit impressed her. I have bought three Coolify, and this is the best one yet. And I have recommended my cousins to buy the new cyber as I have much trust in the product.

The Coolify CYBER continues the great TORRAS tradition of improvement. They have taken the durability of the Coolify 2S and melded it with the expansive cooling features of the Coolify 3. The resulting product makes the Coolify CYBER a reliable heating or cooling method for humanity's demands!

The case to hold the CYBER has also been improved to the similar heavy-duty material used to store the Coolify 2S. An added improvement is the netting within the case, which is large enough to hold the included USB-C charging cable. This makes charging and transport super easy!

You will also appreciate the same reinforcements made to the Coolify CYBER itself. The slight flexibility of the mesh over the fans of the Coolify 3 is gone with the CYBER. TORRAS improved the housing to provide better protection.

The app also features improved control with the ability to choose the percent of heating, cooling, or fan level from the CYBER.

Overall, if you are looking for the best method of heating and cooling yourself in 2024, then the Coolify CYBER is the premium choice!

This is an amazing little neck fan! I just wore it when mowing the lawn and it kept me nice and cool. I plan on also using this when camping and hiking. The neck plates give a nice chill and the fan has several intensity settings. I didn’t realize it also has HEAT! Bonus! If you’re on the fence, just get it!

Part 1 - for new users
I primarily bought the Coolify Cyber for use in my daily commute to and from work. It is very effective in still keeping me cool during the extended portions of my commute when outdoors in the sweltering tropical heat (in Singapore). Its cooling effectiveness is limited if you are directly under the sun without any shade as the Cyber only keeps the neck and lower part of your head cool. For maximum coolness, you need to tuck the lower back lip UNDER the shirt collar instead of following the ads where it is worn over.

Part 2 - Comparison with the Coolify 3
From here, refer to my comparison pictures, Cyber is on top, 3 is at the bottom. They are of similar shape, however the Cyber seems to have improved QC and is better able to withstand sweat (as proudly advertised in Torras promotional material), I sweat a lot and this is a major concern of mine. Will update here in a month or so to confirm if it will hold up.

Appearance wise there has been improvements to the indicators for charging and fan speed/strength and are easier to read now - fan speed/strength indicators are enlarged and in numerical values, charging indicator is in circular quadrants instead of the older horizontal bar. The intake vent holes for the fans have been enlarged for better airflow, and the Torras care team has indicated to me that there are now 29 fan blades total (up from 26 of the model 3).

The finish, while still glossy has a gunmetal grey colour, whereas the cascade black of the 3 looks more reflective and mirror-like.

The graphene cooling plates now have a very faint honeycomb pattern printed on it, not sure if it improves the cooling performance but... plus one point for looking cool. The cooling is more consistent as compared with the 3; the model 3 had occasions where the cooling plate struggled to reach maximum coolness whereas the Cyber always feels cold in cooling mode.

Bluetooth performance is consistent, never experienced droupouts when using the app. Then again, the model 3 was ok for me in this regard (I did update the firmware before first use though)

NOT YET TESTED: The Cyber now also has an automatic adjustment function that tweaks the cooling output based on your skin temperature. I haven't had the chance to test it as I always use the cooling plates at max coolness.

If you already have the model 3 and it is still functional, the improvements to the Cyber don't justify the extra expenditure. However, if you are coming from the 2S or earlier models, CHOOSE THE CYBER.

EDIT 1 - After 1 week usage. Formatting edit. Added some performance experience and internal design details that are not obvious at first glance.
