Simple out of the box
Even if you are not a tech minded person,it is really that easy to set up,very accurate reading aswell,the cheapest I could find anywhere aswell.
Pros
- Easy set up
- Accurate
Great Power Meter
Great power meter. The only downside is that it only measures left side and doubles it. However, it is simple to set a correction factor to account for left/right imbalance. Once the correction factor is set the overall power is very accurate giving very similar readings to my spider mounted power meter
Pros
- Price
- Weight
- Easy to change between bikes
Cons
- Left Side only
- Only compatable with Shimano Hollowtech Cranks
Great service, product as advertised, amazing price.
The product came exactly as advertised in all original packaging, it was delivered fast and the delivery company were easy to communicate with. Great shopping experience will definitely be visiting again.
Simple and effective
Its my second 4iiii power meter after my first one went faulty. I have to say its easy to use and fit but also extremely good value for money in comparison to other products. The App is intuitive and simple, connectivity is very simple and the feedback for your training via a third party software is great. It has really revolutionised my cycling at what is really a professional level product. Given professional teams use it at World tour level it cannot be bad. The highest accolade i can give is that although i had one break on me i bought another to replace it.
Pros
- Simplicity
- Lightness
- cost
- unobtrusive
- fitting
