Great liitle power meter, works perfectly and connects to my device within seconds,, I would not be without one..
Great product (great customer service too from both 4iiii and Probikekit)
Bought the first 4iii Precision 2.0 105 power meter in July, numbers were a bit strange initially but accepted it as it was my first forte in power meters in the real world (I had used a TacX Flow prior). After doing more rides (indoor with the TacX Flow and outdoor) and some trouble shooting with 4iiii (Micheal - Great guy thank you so much for the help), we came to the conclusion that the PM was defective and a RMA was actioned. Process with Probikekit to return the defective product was very straight forward as well, all postage (Royal Mail 48) paid by them. Received a new PM, fitted, works like a charm and the numbers make sense! Great product and service for the price point, an excellent and economical way to get into measuring power in the real world! Thank you to both 4iiii and Probikekit, one happy customer.
Accurate & Affordable Power Meter
My first choice was to go with power meter pedals but the cost of even one sided is more than double the cost of this easy to install 4iii single sided. Glad to now have power readings on outdoor rides now. Pairing a breeze with Zwift and 4iiii app.
First Powermeter
For my first ever PM, it was easy to setup and get started. Within 30min of delivery, it was on its first ride. Can't wait to make and break some personal records.
Great product
Have had this power meter for over a year and I have found it to be great. The feed to my bike computer connects easily and I do not find that it drops ever. Highly recommend if you are looking to bike with power
Delighted with price and results
I didn't think that I needed one of these, but the reducing price and the persistence of cycling friends tipped the balance. Now I'm hooked and it is an essential tool. First I have shifted from heart rate training to power and am finding huge benefits from the results. Secondly I am now using group ride apps and enjoying my winter indoor training much more. The 4iiii Precision unit couldn't be simpler to setup and use. If you have a gravel bike be careful to check the clearances. It has integrated with everything that I use and a pleasant surprise was that it clicks straight in with my Polar V650. Single side does not give me any apparent limitations in data.

I like the power meter it was a good price and works well and was easy to fit and set up. It connected to my Wahoo Bolt in a few seconds.
Recommended.
Can`t say anyhthing, if u r looking for a cheap and reliable power meter don`t miss this one.
PowerMeter 4iiii
I was so pleased with the first one that I bought another for my gravel bike. At l last I have power figures for my off road activities as well as on road. No more Strava estimates. 5 minutes to fit and a small spacer gave chainstay clearance on my Canyon Grail on Ultegra crankset.
PowerMeter 4iiii
Finally I bit the bullet. The cheapest option was a 105 single sided left crank for my Ultegra group set. I can't say how delighted I am. My reservations about single sided have gone completely. I've adjusted the calibration to account for a discrepancy in my left leg output and to be honest it's just what I need. Fitting and setting up were super easy. Battery life seems good and it's no problem carrying an emergency back up CR 2034 as they weigh nothing. It took one spacer to give me chain stay clearance on my Canyon Ultimate. I have instant feedback on my effort and now resist the desire to go harder than I should during recovery rides. I also get an immediate comparison between my heart rate and my power and can see change over time. Why didn't I do it before?
