4iiii's most powerful unit yet, compressed into a smaller, lighter package and featuring Apple Find My, the PRECISION 3+ Powermeter is a proven choice of pros and amateur riders alike. Whether you're fighting for a qualifying spot in Kona, logging countless hours on virtual riding platforms or looking to improve your time in the local KOM segment, you want accurate and reliable tools to unlock your potential. With up to 800 hours of battery life, an automatic terrain selector, +/-1% accuracy and backed by our industry-leading 3-year warranty, the PRECISION 3+ Powermeter will be your trusted tool for years to come.

HOW IT WORKS.
The PRECISION 3+ Powermeter is so much more than a power meter. It is your training partner that gives you peace of mind. While cycling, your PRECISION 3+ Powermeter sends watts, cadence and calories to your navigation of choice. When the power meter is not in use, Find My is enabled and your power meter turns into an Apple Airtag. You can add your bike and view its location through the Apple FindMy app on your iOS device.

FEATURES
APPLE FIND MY
The peace of mind of knowing exactly where your bike is, wherever you go.

800 HOURS OF BATTERY LIFE
With up to 800 hours of battery life, using the same CR2032 button cell battery, you won't have to worry about replacing your PRECISION 3+ battery for years.

ACCURACY IN 3D
Not everyone has the perfect pedal stroke. With +/- 1% accuracy, the 4iiii is the only crank-based power meter that uses 3 strain gauges to measure all the forces in your pedal stroke.

AUTOMATIC TERRAIN SELECTOR
Detects the terrain you ride on for more responsive cadence and power feedback/data. Ride confidently on the less traveled roads.

Does exactly what you need it for.
I like these adapters. Some pros: * There's a blue light to show that power is coming to the adapter (great to ensure you've plugged it in correctly) * The gap at the bottom of the plug ensures that it works with a phone in a case. (I tested it on an iPhone 15 pro max) * The connectors are solid good click when connected. * The housing is solid aluminum (no flex or seams, etc) * There is a little label on each that shows how much power or data can go through it. Use case: * Allowing you to use your phone on your bed while the phone is sitting on your chest (and still plugged in) * For the USB-C to female USB-A female adapter, the page shows that you can use this to connect a flash drive or a regular USB-A cable with the other end going to your peripheral (like a keyboard or game controller) Overall, this is a great item to own in your gadget bag.

They work.
They work fine for my sort of "specialized?" use. By relieving the strain on the laptops USB ports. Hopefully, prolonging their lifespan. Do wish they would make the edges and corners a bit rounded.

I can use my remote again
Style: 1 to 1 IR Repeater
I added a center channel speaker, and it was partially blocking the remote sensor. This solution works like a charm and has an easy setup. One end points towards the existing IR, and the other end goes where you are going to point the remote to. The only suggestion is to include a USB connector with the product, so I don't need to find one.

Very good signal repeater
Style: 1 to 1 IR Repeater
Fantastic product! I have a center channel for my surround sound that blocks the infrared sensor on my Sony Bravia TV that never works. I always have to get up to turn the TV on or off as well as other functions. So I purchased this product and it worked like a charm. Very simple to install, took less than 5 minutes . I didn’t have no compatibility issues. It was plugged play . Simply stick on the transmitting sensor by the receiving sensor on the TV and then the extended sensor for receiving from your remote control put where you would like it, lastly plug in the USB plug into any 5V power block and you’re done. Now I have no issues with range with controlling my TV, which is great.!👏🏼. Definitely a good product. I would highly recommend…

Easy to Set up
Style: 1 to 1 IR Repeater
Works great. Have Sonos playbar mounted behind TV and it does not support eARC, only IR, for use with AppleTV remote. This solved problem.
