Reviews over the

4iiii 105 7000 Precision 3

Quick installation, very good price and great in combination with my Wahoo Roam. Perfectly adequate for me as an amateur athlete!

As described above in pluses, top product for nice price.

Pros & Cons

Affordable power sensor with more than satisfactory accuracy. Quick, easy calibration. Easy to dismantle and assemble if you want to move from one bike to another. Thanks to the printable template on the site, I was sure that the crank would be compatible with my Orbea Orca Aero. Impeccable delivery and service as usual.

The powermeter is easy to mount, for me the hardest part was taking off the pedal as it was tight. Connects quickly to the app + any other apps you use. Battery was already at 92% though

Pros & Cons

Very quick and easy to install. Connected right away with the calibration application and my Wahoo meter.

After easy assembly and connection, it is immediately ready for use. Because the power meter is unidirectional, it is recommended to average out the power to take out the fluctuations. A fantastic upgrade!

Pros & Cons

Deplorable customer service never received my parcel and does not reply to emails

I am very satisfied with my the purchase of my first power meter. I chose this power meter because of the positive reviews and the attractive price. The product was delivered quickly and I have been using it for a month now. The power meter works very well with my bike computer and provides valuable information that allows me to train in a different way.

Pros & Cons

Works perfect and decent price point for the product

Pros & Cons

Perfect option for potentiometer on Shimano 105 groupset.

Pros & Cons

I bought it to work with watts and cadence. Very good material, nice finish, easy to install and pair with my Garmin 520. Thank you Mantel for this product. As for the sensor box, it's compatible with giant tcr advanved pro disc 2 from 2022.

Pros & Cons

Satisfied with my purchase.

Pros & Cons

Reliable powermeter at a reasonable price and with slim profile so that it fits even on frames with little space between crank arm and chain stay - top!

Pros & Cons

Automatic synchronization and calibration with my Garmin Edge 530. Very easy to place on the bike. Delivery in 4 days to Spain.

Pros & Cons

For years I only rode with a heart rate monitor. Got used to power via an indoor trainer, and had read and heard a lot about training everything on power. This power meter was the ideal option for me: (1) not too expensive; (2) easy to install myself, even for a clumsy person like myself; (3) good reviews, reliability and precision seem okay; (4) what won me over with this version compared to an older version is the long battery life. Power meter likes it very much so far. Main insight is actually that you still need to ride your endurance rides a bit more slowly than you would think based purely on heart rate; it feels very slow but over time you get much stronger. As mentioned, very easy to set up. Whether the battery life is really 800 hours I have yet to see, but for now everything is fine.

Pros & Cons

We have to get used to training on power but it will work. New motivation again.

Pros & Cons

The power meter is not only the cheapest on the market it also works m.M. after accurately and is reliable. The weight is negligible and if the specification of 800 operating hours are correct, perfect!

Pros & Cons

Very good product with a good value for money. In addition, the purchase process was unbeatable, they resolved very quickly and efficiently the doubts I had, and once the order was placed, it arrived very quickly and in perfect condition.

Pros & Cons

Very easy to install and calibrate. After 2 outings, the data seems very consistent.

Pros & Cons

Easy to assemble and for first training after power

Pros & Cons

I was looking for a power sensor that was affordable and above all compatible with my aero bike, which has very little frame clearance at the crank passage. I've followed the various reviews of this new version of the 4iiii sensor and I have absolutely no regrets. I had no trouble fitting the 105 version of the 4iiii sensor to my ultegra crankset, and the weight of the cranks was exactly the same on my precision scale (207 grams). Only the 4iiii application for updating the sensor firmware gave me connection problems, but these were easily solved with another, much more practical application. Beware also of the state of the original battery, mine was 70% good when I received the sensor. A good idea if you want to take it easy.

Pros & Cons

Good power meter, easy to setup and pair with other devices. Happy with the purchase.

Pros & Cons

Very good product. Very accurate. I have compared it with the garmin vector 2 and my roller and it goes Dino.

Pros & Cons

When the ride is interrupted, the sensor does not immediately go into standby. When I leave the wheel clock and pedal immediately re-couples.

Pros & Cons

Use it every day

Pros & Cons

Product is delivered quickly in a nice neat box. Because the meter turns on by movement, the power meter is no longer 100% battery when delivered, fortunately it lasts 8x longer compared to precision! Nice sleek design and very easy to use. After mounting on the bike and downloading the app from 4iii, the meter is connected to your bike computer within a few clicks!

Pros & Cons

Excellent power meter, easy to install and calibrate via computer or dedicated app. It uses both bluetooth and ANT+ standard. For those who do not do professional use but want to have more data available and still for amateur use I recommend it. Purchased on Mantel at a great price.

Pros & Cons

The new model of the 4iiii meter is simply amazing, accurate, lightweight and with a super battery. Tested it already in all weather conditions, always flawless. I also did the FTP test and it was as accurate as the test done the lab, difference of 1 or 2 watts. All this is amazing at a really low price for a brand new model and just recently on the market! I would recommend it to everyone, not just those who want to spend cheaply on a powermeter.

Pros & Cons

arrived on 13/5 used immediately for 4 consecutive days, even with rain, so far no problem, accurate in measurement, I feel recommend it, it is a brand new model with more accuracy than others, at a super competitive price, super battery.
