i have Rockrider 300, from past one month i am using it is good and i am happy.
working great
A simple, sturdy and easy to install computer. Can be installed in a jiffy without need of any tools. Moreover, can be easily attached or detached from your bike without a single scratch on her. I have it on my RR 5.1. Rain or shine, its always on the cycle. Been using for more than 6 months with no issues. Value for money.
A simple cycling computer which tells you what you really are looking for, current speed, partial & total distance.

The basics at the convenience of wire-free 1min. setup time. The large screen and font is easily visible even in direct sun. Although a backlit would have been nice.

Those who are looking for additional features like Avg. speed and top speed should opt for Count 8 while those who are looking for just the basics Count 4 is exactly what you should have.
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.

Response of the brand
Hello,

Sorry to hear that the product hasn't met up to expectations, I would suggest you return this for an exchange or refund. In regards to the sensor, the magnet must line up to the arrow on the sensor and be within 5mm otherwise it will not get a reading on the display.

Used for More than 1 year
This is the second I've bought - first for my road bike then a year later, another for my MTB. Price won't break the bank. Doesn't have all of the silly functions that you'll never use and are never needed. I'm >60, have many years experience and can truthfully say that this is an excellent piece of kit.
