Reviews over the

4iiii Precision 105 5800

Excellent good value power meter. Good accuracy. Fitting instructions and Android app could be better.

Pros & Cons

Great for training, and pacing yourself on longer rides and hills.

The power meter works well with the wahoo element bolt. But the app it comes with is awful, you cannot really use it. So unless you have a compatible computer you can use don’t buy this power meter. It is accurate within a torque setting of 10, compared to 2 different quark power meters. Very good price for what it is compared to other options on the marketand so light!!

Pros & Cons

Great service from mantel and the product is super now i can train properly and accurate

Pros & Cons

Top quality, easy to install power meter! You won't go wrong with 4iiii. Very quick dispatch and delivery as well as being the lowest price online!

Pros & Cons

After 2 weeks - easy to use paired in few seconds with garmin &/or polar v800 ant+ and BT in paralel. Good Basic left leg power measure, good value for money. Stable and ( I hope precise :) power reading, however when hi-cad excercises over cadence 160 sometimes shows 0 for one second when cadence is more than 150-160 but it is not big issue. I would buy again.

Pros & Cons

This is a great value power meter. So far (~500 km of riding) the measurement has been reliable - especially compared to my previous power meter, Stages 2nd gen. That being said, the measurement seems to fluctuate more than with Stages.

Pros & Cons

Connects seamlessly to my edge 820 and fenix 5 plus. Had no issues so far on my daily commute. Great service with quick delivery and constant updates on delivery times. Add to that the best price available online so win win.

Pros & Cons

Easy to self install and links up to my Garmin just mint. Would recommend, especially at the price Mantel sells for!

Pros & Cons

Very Fast delivery.

Very easy to fit the crank with the meter which is small, light and discrete. The instant feedback (of power) visible on my recording device is both fascinating and dismaying!

Pros & Cons

Great price for a good product. Very happy to be training using power data and at a reasonable price. Linked the 4iiii in with my Elemnt Bolt and they work great together. All very easy to set up. Mantel price good and delivery was swift. Happy.

Pros & Cons

Product is fantastic at very competitive price. Delivery was delayed but nothing major!

The power meter crank is very easy to swap between bikes and easy to set up.

Pros & Cons

Easy to fit and calibrate. Seems to be accurate

Delivered quickly with good parcel tracking. Once received It took 5 minutes to fit and then paired with an ELEMNT Bolt and calibrated immediately. In 10 minutes from opening the box I was riding with power over Ant+ indicated. On Zwift it also gives cadence and Watts readings over Bluetooth simultaneously. This is a brilliant power meter at a great price. I am very pleased indeed and would recommend both the 4iiii power meter and Mantel to everybody.

Pros & Cons

Direct replacement for old crank arm and easy to set up. Training is much precise with power. Top product.

I have cycled with this power meter for only a few days, but already found it invaluable for training to improve my FTP.
