I used the "Margin c606" speedometer for the last season, and
around fall I needed a power meter so I bought "Margin PES P515" additionally and am using it.
I don't think the new Margin c706 has much difference, so please just take note.
-- I added an image but deleted it because I couldn't complete the post
[Advantages]
# Good value for money. Very affordable.
The difference between the new c706 and the lower model c606 is in the electronic hybrid/ambient light/screen size
Since the new model came out, c606 used prices are traded below 100,000.
# The mobile management tool OneLabFit UI is quite good.
Transferring gpx files from Kakao Map, configuring the screen, and setting various things is quite convenient.
The data display screen is also well organized.
If you look for features, there are many and they are well segmented.
# Real-time power graph
Garmin's power graph is 3-second average, while Margin is real-time.
When suddenly doing intervals to overtake
Margin: 200 450 600
Garmin: 200 240 320 380 450 520 600
Like this, Margin changes dramatically all at once.
Garmin is average so it seems like over twice the reflection is slow.
Maximum power also comes down quickly, so Margin's maximum power hits exactly 700, 800W
Garmin goes up and shows average so it just comes down. The response is also a bit slow.
# Battery lasts a long time.
I'm currently using Garmin 1040 Solar.
Solar or whatever, Margin just lasts a long time because it has a large battery capacity.
[Disadvantages]
# Notifications don't work.
I'm using the Galaxy S25 model.
If you look at OneLabFit reviews on the Google Store, there are many reviews saying S26 doesn't get notifications, Folder/Flip doesn't work.
It seems like it doesn't properly support Samsung ONE UI.
When installing the app, the notification permission request doesn't appear.
In the app settings, the notification settings screen appears fine, but in the Android Notification Center, the option is completely turned off.
Last year it only came with calls/text messages.. but recently it doesn't come at all. It seems something was updated.
The new c706 has the same problem. (I don't know why YouTubers don't mention this)
I just used it by resolving it with a Samsung smartwatch.
# Map data issue
Like most speedometers, Margin also uses open-source map data, 'OpenStreetMap' data.
If you download this, it comes to 38MB.
Margin has various features using map data, but it's not satisfactory.
For example, Climb Pro operation usually doesn't work.
Bukak works, but Namsan doesn't or..
Since even places like Namsan don't work, basically nothing works.
For reference, Garmin Watch Map is 368MB and the map data is about 10 times larger.
Of course, for Garmin search, most buildings/bridges etc. are named, and building shapes are detailed.
Besides what's shown, it seems slope information has also been significantly corrected.
Garmin operates Climb Pro annoyingly even with errors, and basically all uphill areas appear.
Rather, it's bothersome so I wonder if I should turn it off a bit.
I think this might be a limitation of devices using OpenStreetMap.
[Q&A Board] Margin c606 Climb Pro
==================================================================
I'm a commuting user so notifications are very important (calls/text messages, Kakao Team chats, company Teams)
I was stressed because of the power meter so I just sold Margin.
If the notification issue is resolved, (it hasn't been resolved for a year)
Notifications are not that important
If you use a normal power meter and Climb Pro is not important, it's really good value.
If the power meter was normal, I don't think I would have changed the speedometer.
