Not on;ly is it one of the most accurate power meters on the market, it's also one of the lightest, weighing just 9 grams.

So, whatever computer, training device or apps you use, you won't need to worry about integration between your new power meter and your current set up.

Accurate data, improved training
Super quick delivery and exactly as described. Took it to my LBS to fit (probably could have done it myself - instructions made it sound super easy) and have enjoyed the extra info the power meter feeds to my Wahoo Bolt. Cadence and power info is helping lift my training and I am already noticing more consistent effort during rides, particularly on hills. Really happy with this purchase and will buy again from Probikekit.
It just works
Had a crank based power meter that stopped working. This is nice and simple and seems to give consistent power figures. Defo recommend and don’t listen to the dual sided power argument Sky used single sided power for years and won everything. Great value particularly with a voucher code. Or just buy the 105 version
It just works.
I had an old pedal based power meter - it was always dropping the signal, chewed through batteries, was a pain to clip in and out of, and weighed a metaphoric ton. Thrilled with the 4iiii meter - a snap to install and calibrate, was able to re-install my old (but brand new) Ultegra pedals. Not only does the power meter "just work", the sure and consistent feel of my Ultegra pedals removes that old aggravation. Price, ordering, and delivery were all very easy. Added benefit: Love supporting a small Canadian company that is producing such a great product.
Efficient and well priced
This is the second one of these I have owned ( I sold the last one with my last bike). For a single sided unit it is very good and also for the money as they are well priced compared to others. Its within 2 watts when I compare it to my smart trainer etc and syncs seamlessly to my head unit. Overall I'm very happy with it and would recommend it to anyone who is looking for a good entry into power meter based riding and training.
Power meter
Just back from the first ride. Sooo satisfied. Easy installation, calibration and pairing also with my Wahoo ELMNT bolt. Working like a charm,. The only thing is Strava stupid calculation which never the less using their algorithm and ignoring data from power meter ... But who cares for Strava politics. Strongly recommend, the best option for pristine PM on the market!
Power Stats
Quick reliable delivery, easy to fit and working well. Love the stats!
19 months of perfect power performance
Long term review: Bought this tbh as it was the cheapest proper power meter available at the time. It has been amazing. Accurate against my Tacx Neo smart trainer within 5 Watts. Batteries last a couple of thousand km. Never drops the connection to my Garmin Edge 820. Made pacing an Everesting much easier.
Absolutely brilliant
Probikekit had the best price for this 4iiii R8000 power meter. It's the first time I have used it and found it very handy at pacing my rides, especially on climbs. They say the accuracy of the unit is very good but since its my first power meter I am not too bothered as the readings are solely for myself to help me pace my efforts. I guess, that's the main use of a power meter anyway so no need to spend any more for double sided ones. And stay clear of the stages power meters that's what I've been told. 4iii is, the one to buy!
Works great
Simple to fit, even easier to calibrate, working great, no power drop outs.
