Compared with the other comments, I confirm the poverty of the documentation: 1 A5 page! On which the third explains how to encode the videos, but nowhere is it said how to change the volume. There are of course the usual PDF on the mini-CD accompanying but in English ... On the site there is the doc in French but for the mini model, the M6, more expensive, so all the described features are not present on the Music Card, and the keys are not the same. Must juggle all this to find out how it works, because everything is not really intuitive. The absence of strap really petty, but it is nevertheless nice to find a snap point, all do not.
At first I thought it was not working, it comes completely discharged, it must be loaded for a long time he agreed to come on. Even then beware, it takes several seconds before we see something appear.
I deplore the operation of the USB port: one can not listen while charging only transfer files. So when he is discharged he should stop using it for 3 hours ... Okay it's essentially made to be mobile, but the office is not bad to recharge by listening.
The keys are -assez- thoughtful and pleasant to use (the concept is similar to a laptop touchpad, but in 2D), but the cursor is hyper sensitive and it takes getting used to. Merely slide the device in a pocket disrupts the sound. So either you become a virtuoso of the lock button or deactivating the sound adjustment function, but it must go through the menus to this and this almost forbidden to change the volume easily. I would say that it lacks a little feature in the firmware, for example, to click (tap) on the slider before it allows adjusting the volume. Furthermore the (single) for go to the previous or next track, which implies a long press to reverse the direction of travel is also poorly designed: a short press to go to the next, long for the precedent would easily exploitable, but not, as is the case briefly to go where it is set, and a long to reverse the setting. What makes you never know if you go forward or backward ...
No problem for the transfer of sound files, images, and text. Changing wallpaper images is easy to do but you have to read English or adapt the French doc found on the website of Danelec. The recording works well. I have not tested the video. The songs lyrics display is totally inoperative. U remainder of procedure other model not updated? ...
Text files (pompously named EBOOK) is also poorly designed: no recognition of accented characters encoded in UTF8 (as the music part displays without any problems securities seized in Greek or Cyrillic). And more and no directory is intended for that, we must do it ourselves ... Why have forgotten it?
The organization of audio tracks is well done, it quickly finds what one is looking, but it is impossible, as on almost all of these devices display the tag describing the style of music.
The sound quality is at the rendezvous, not as good as on an I-Pod, but for that price it is really good.
The autonomy against me seems quite illusory. Among other things I have to unplug the device once it announces full charge, and then reconnect to resume the load, and I never had the autonomy announced.
I maintain: mixed opinion ... Device cheap and effective, but it could have been much better with a minimum of effort.
