## XFR Reviews in United States

### ***** "Great system"
It’s a great system that is easily set up and I love the fact you don’t have to call a cold range to set it up.
-- Bluesguy59, 2025-03-26

### *---- "Does not work with Apple USB-C to headphone jack"
Needs an update to work with iPhone 15.  Did try all volume setting. Does work with older iphone models for me.
-- Datadude77, 2023-10-25

### *---- "Need a new update"
Can’t use it on iPhone 14 pro max
-- Looper-lawless, 2023-05-19

### *---- "Hard to use phone adapter."
Rate it 1 star
-- chasmoo, 2020-10-13

### ***** "Brilliant app for recording and editing shot groups using Magnetospeed V3"
I have been using the Magnetospeed V3 for about a year now and it is without any doubt the best chronograph on the market.  I also purchased the Magnetospeed XFR and connected it to my iPhone 11 Pro Max using the Apple lightening to 3.5mm connector.  It works perfectly.  

It is so cool to be able to capture my shot groups on my iPhone while at the range and edit and make notes as needed.  Great product and great app.
-- caoimhinog, 2020-08-13

### *---- "Still new to MagnetoSpeed, but irritated already."
Bought a V3 recently, still just playing with it to get it working. Started with 45 Long Colt, had some trouble getting readings. Couple of tries later, got readings, but they were not believable. Results should have been in the 700-900 FPS range, but I had readings of 2500, 1700, 1100, etc. Called MagnetoSpeed, they suggested setting sensitivity to 1, which I will do.

Then plugged in the XFR, and played with that for a couple minutes. During this time, I was nagged multiple times in a few minutes for a review. There was no apparent way to say “not now” that lasted more than 30 seconds. 

You want a review - here it is......nagware rates a 1, regardless of how good the rest of the product is.
-- Richard_R544569267, 2019-08-14

### **--- "Unreliable"
The device and application do not connect to each other 100% or even 30% of the time.
-- spd0219, 2019-06-20

### *---- "Doesn’t work with iPhone X"
Waste of money. It won’t connect using the iPhone headphone jack adapter
-- Manthonyc, 2019-04-06

### ***** "Magneto speed XFR"
Works great, company has great customer service!
-- SkyPilot JRT, 2018-10-28

### ****- "Great app!"
Great app, very simple and straightforward.
