If you are a beginner you can go for it cause it shows you basic information needed for cycling. A bit disappointed with the manuals.
Great

It does what it should. Reports speed, time, distance traveled for a trip, and distance traveled in total(let's say since purchase if you haven't reset). It does require a bit getting used to, didn't receive any manual, which was disappointing. Also, plugging and unplugging from the bike is difficult. I am always worried that the lodge(the pin on bottom-left of odometer) may break if too much force is applied. It hasn't broken, though, but since it's plastic and does require a good amount of energy to plug, the worries follows. Decathlon should train once or twice on how to plug-unplug for amateurs.
Nice interface, Highly precise, good features
Absence of how-to-use manual
Good

Used for 3 to 6 months
I am a decathlon loyal customer but really disappointed by the design of the product count 8. The count 8 has-been removed from the website thereby I have to write my review on the similar product. While fixing the sensor the store guy set the distance between the magnet and the sensor less than 3mm as it wasn't detecing the wheel rotation.One day during the ride the sensor came of and a car ran over it..The design needs to be improved as for better hold on the fork and sensing at the distance(5mm) . I was lucky that the sesor didn't hit and damage the expensive road bike wheel.
Nothing
Bad design
Response of the brand
Hello Pranav, 

The store representative has done the right job in installing the sensor because the sensor has only a range of <3mm. Unfortunately, this is the best range of the sensor at this price point.  However, you feedback is valid because it is possible that the rims tend to bend while riding in rough conditions and there is a possibility of the of the sensor getting damaged. This problem can be solved if the sensor is angled away from the direction of rotation of the wheel. I will forward your review to the brand and try to improve the product. 
Thank you for taking the time to give us your feedback

Used for More than 2 years
I have 3 of these, one on each bike as a backup so I don't have to look at my app on my phone or watch. Easy to fit and the computer has a few options to how/where its fitted
good price
You need to know how to fix it
At the beginning i thought it does not work .. but then I read one of the replies which says the magnatic piece facing the small arrow in the sensor and bend the sensor so close to the magnatic piece then it will work

Regards
Excellent

Cycle computer does not work
Used for 1 week or less
I set this up per the instructions. The instructions are quite poor but it is not that complicated. However I spun the wheel around expecting the speed to measure and nothing happens. The sensor on the wheel shows a green light. The computer on the handlebars has been set up. The wireless connection between the two does not seem to work. This is both frustrating and disappointing. The video shows the computer working by just spinning the wheel. It is a shame there is no way to test what the issue is. It simply does not work.
Response of the brand
Hello Paddy,

Sorry to hear you are having issues with the Cycle Computer. In regards to the set up, you need to make sure the magnet sweeps less than 5mm away from the sensor, it also needs to be at the corner of the sensor where the arrow is located.

If it still doesn't work then I  would suggest you return it to your local store for a refund/exchange.
