The touch screen works perfectly, even if of course it is not at the latest smartphones (integrated mini stylus to the strap is really handy) and, contrary to what I read, the wireless setup is simple as on any other device equipped with this technology (a nickname given to the NPC, infrastructure mode is selected, connection to the box by entering the password and basta).
In terms of its main weakness (in the tests I've read), autonomy, I did not step back. I can just tell you that it took several hours (the fiddling in every sense by including wireless transfer) for several hours after unpacking (ie with a partially charged battery). And nothing prevents you to buy a second, which is almost systematically all regarding me. Wifi is certainly detrimental to all devices that are filled but note that it is only activated when it is used.
Regarding smartphone connection apps, the iOS version works perfectly well, whether on Iphone or Ipad. The Android version seems to have against a much harder (but my S3 is equipped with a custom ROM and therefore not truly representative).
Last remark, the Mini USB port is totally standard which is a definite plus for me.
In conclusion, I highly recommend this product with scores on a well-known test site seems totally unjustified me, especially compared to its price.
