华为手环4和4e：两个一起用也没什么问题

At prices of about 39 Euros (~$42) for the Band 4 and 29 Euros (~$31) for the Band 4e, the two fitness trackers belong to the more affordable fitness bands. By the way, the Honor Band 5, which arrived in fall, is also part of the same price segment and even more affordable by now. Those who are looking for a simple tracker to motivate themselves to move more cannot do anything wrong by choosing those two devices. Those who also value the notification functions should choose the Band 4. Even if this functionality is not a priority, it can quickly become annoying to get informed about a notification, but then have to grab the smartphone to be able to read it. 

Band 4 and Band 4e by themselves are not much more than simple fitness trackers, but they can complement each other when used in parallel, particularly during training.   

While you will find many fitness bands similar to the Band 4, despite its simplicity the Band 4e offers a functionality with its accurate sensor, which is rare to find in this price range and could be quite useful for runners. The combination with the Band 4 as in our test, or perhaps also with the Band 4 Pro with GPS, might be interesting for the corresponding target group of runners. Of course the prices will also add up to about 70 Euros (~$76) together with the Band 4, and more than 100 Euros (~$108) with the Band 4 Pro. However, at the end, even in the professional segment - for example with a Garmin Fenix 6 - you can only get the additional sensor data using external accessories.

Those who still have an older tracker from Huawei should also be able to combine this in parallel with the Band 4e in the app. In addition to older Huawei bands, the app also lists some devices from Honor. However, we were unable to try this.
