Terrible product/terrible customer service in my opinion

My reasons for dissatisfaction with 4iiii are: The product (dual factory-installed power meters FC R 9200) was defective and not fit for the intended purpose; 4iiii appears to have misrepresented the obvious design defect in the product (ie defective, disintegrating plastic), the alleged cause of the problem, the alleged redesign of the defective plastic, and the time required to repair the defective product; 4iiiii has wrongly blamed the cyclists for the defect, claiming it is due to cleaning agents (my bike has only been cleaned with Dawn dishwashing soap yet 3 casings have failed, even after an alleged redesign of the plastic); the warranty is illusory; the express and implied warranties have been breached; the customer service department is nonexistent or appears to be intentionally unavailable; the customer service representatives are vague, nonresponsive, unhelpful, uncaring, oblivious or unconcerned about the needs of a cyclist, and at times appear deceptive. The dual power meters, which were standard equipment on my S-Works Aethos and not chosen by me, have rendered my bike unusable for over a month while being “factory repaired” (assuming they now work), not to mention the many months I had to ride without any operable power meter because these did not work but were still unsightly, disintegrating blemishes on the bike. In my opinion, 4iiii is the worst cycling company, and maybe even worst company in general, that I have ever experienced. I raised all of these concerns numerous times with 4iiii and never received any escalation or relief. The foregoing are my opinions based on my particular experience, not statements of fact.

Outstanding Power Meter

I have the dual sided Precision Pro on my Ultegra 8000 with 50/34 crank. Works flawlessly and appears to be accurate. Customer service has been top notch as has warranty support. I am waiting for the development of the Precision Pro dual sided power meter for Ultegra 8100 with 50/34 chainrings. My new titanium bike with Ultegra Di2 will be delivered in January '24.

Dura-ace 9200

Process took forever! The drive side looks installed a bit sloppy, kind of far away from the crank arm. When connecting to app would only pickup one side, batteries supplied was low on one side and completely dead on other. Took a long time to fix the issue (trying to figure out which battery was dead) and get the unit to register as a dual meter. Hopefully all issues are fixed now.

Dura-Ace FC-9100 Factory Install

I have been using this power meter for a few months now and can say without a doubt that the entire process was seamless. I was worried about taking my cranks off and sending them away, but they made the entire process easy and simple to do. I could regularly look to see where my cranks were at in the install process and track the shipment when they were being sent back. Once I installed them on the bike, it took about 15 seconds to get it paired to my phone, and Garmin head unit. It could not have been easier. Power readings seem to be accurate and has taking my training to a whole new level. I was use to doing structured workouts on Zwift based on power, and this makes those same work outs easy to do outside. Would highly recommend this power meter!

Unit not working and costly repair

Received a defective unit. Tried to troubleshot with the service representative who was nice and helpful hence the 2 stars (instead of 1). Troubleshooting did not work ...
I had to return the unit (which was brand new!) to the factory for repair. I lost my bike for over 2 weeks since it was factory install on my only crankset. I had to pay for the shipping which is costly for an item of such value and with all the packing to protect the crankset. In the end, it costed me more than buying the whole package : new crankset with the power meter. I would not recommand factory installation. You better buy the whole thing new from the beginning. If I had known, that is what I would have done in the first place.
