I wanted to give a review of the magene c606 i ended up getting after about 15 hours on it.
It's extremely frustrating because it clearly has potential to be pretty much perfect. It just needs climbpro, strava segments, the ability to import map layers of our choice because the default one sucks (and this would probably warrant an extension of storage. 4GB is enough for such a blank, undetailed map but probably not more) and most importantly the total execution of their phone app developer team by firing squad.
It really is almost perfect in terms of hardware, it's quite heavy but the screen is by far the best I've used, touchscreen is responsive, GPS data is flawless. It is really really good.
But the phone app (which is required for everything) is not just a disaster but straight up false advertising: it just doesn't work on android. Took an hour to make an account, another hour to pair the computer, and it randomly unpaired it. I didn't do anything differently, I just spammed over and over until it worked, as customer support suggested. The app is buggy, when it "works" it barely works, the app store review is full of 2 year old 1 star reviews that mirror everything I say, so they clearly don't care to fix it. Supposedly it's okay for iOS but for android, steer clear of ANYTHING magene that needs their app.
Their customer support gives you the fake platitudes and concerns of western customer support but with chinese delays. It COULD be so good but they don't care.
TLDR: Hardware is almost flawless, map layers aren't detailed enough, it lacks a climbpro-like feature, but most importantly the phone app is so bad I want whoever made it dead. Avoid. I'm returning mine
