## Qalvin Legacy Reviews in United States

### ***** "Works"
Mostly use it to test battery voltage.  Works fine for me, sometimes a phone reboot is needed to find the device.
-- Kevin_Indiana, 2023-06-14

### ****- "Worked to reinstall firmware"
My Quarq for Cannondale worked flawlessly until one day that it could not connect to my head unit (Wahoo Bolt). The Quarq Led would continuously blink. Qalvin Legacy does not communicate by iPhone to Quarq PM. I spoke with Quarq customer support and they said I must use either Windows or Mac PC with an Ant+ dongle.  So, I bought an Ant+ dongle from Amazon for $15. I downloaded Quarq Qalvin Legacy onto my laptop, but all fields other than “about” were greyed out. The Ant+ dongle would not change anything. My Laptop is Windows 10.  So, next I tried an old desktop that I keep in the house, but never use that still had Windows 8.  This time, when I inserted the Ant+ dongle into the USB, all of the greyed fields lit up! I entered the Quarq sensor number and selected install firmware and it installed successfully in about 1 minute. This worked flawlessly and my power meter is working perfect again.  This was my experience with Quarq Qalvin Legacy. It is old and required an older version of windows (or perhaps just needed to be a desktop instead of laptop?).  This worked.  I learned that it won’t work from an iPhone or an iPad, and in my case, even a newer laptop, but it worked perfect on an older desktop with Windows 8. Hope this helps someone who needs to reinstall firmware on a legacy Quarq, just like me.

### *---- "Does not work."
It does not function, only opens the help link to the browser, and the target website is 404.
-- iPaloAltan, 2021-04-18

### ***** "It does work!!!"
This app works if you have an Ant+ dongle that plugs into your phone. I purchased a usb Ant+ dongle and used my Mac instead. You can download the MacOS version of this app at the Quarq Legacy help website. Cheap and easy and, most importantly, it still works as of March 2021.
-- Frank Sheed, 2021-03-26

### *---- "horrible app. Worthless"
It simply doesn’t work, and I can’t update my power meter firmware. Thanks for that Quarq!
I guess it’s time to consider another brand.
-- Rod@900, 2021-02-15

### *---- "Doesn’t work"
Downloaded app. Can’t search for a power meter or enter the I’d no. Years ago, I used the app to pair a quart Elsa rs. Now, nothing.
-- Bsz543, 2021-01-25

### *---- "Worthless"
Won’t work.
-- You know, like, 2020-12-04

### *---- "The app don’t do nothing."
It doesn’t work for nothing. Forums about the product are bad and there is no support for older Quarqs.
-- ldizai, 2020-09-26

### *---- "Doesn’t work"
Can’t search for power meter. Nothing on the app works
-- highimwizdumb, 2020-06-11

### *---- "Can’t even use it"
Downloaded app, and the only thing I can click inside the app is the “Help” link, which redirects me to a webpage of Quarq that no longer exists. 
I deleted the old app for this one and I can’t even click “search for power meter.”
