I like it :-) The core could have been slimmer, the clock seems a bit clunky. Slightly less weight would be nice, but the overall fit. The gray metal anthracite color looks good, the bracelet like. Installing the SD card is tedious, the sim card can be installed relatively easily. 4 of 5 stars
SIMCARD and operation:
Compared to the pure Bluetooth SW offers the standalone variant a distinct advantage, a smartphone is not required. My phablet (Lumia 1520) remains the faithful companion, with specific activities a la sports in the studio now in the locker. Phone, SMS, Skype, Whatsup, MP3 player, Facebook, etc. ... I can be reached even without Smartphone. Ok, the answers one should because of the small keyboard input hold short ... but it works. However, what does not work: Without reading glasses is nothing (in my case). What does not work when Sony SW2, does not work in the Callisto 100 also. I have good reason a phablet :-). With glasses, however, everything is ok. A pen is missing in the delivery, at least for me.
The apps mentioned above all work, no problems. Facebook, WhatsUp and Skype running. Gmail / Calendar and contacts sync ... you stay up to date. An FM radio I downloaded works without headphones. With Skype voice quality video is limited on both sides, ok. Whereas you had to arrange the clock, would you look back even into the picture. Photos knipsen works limited, you have to press down the back of the hand. The quality of the images are different. Outdoors well under artificial light so la la. Except for NTV, mirror I have no other apps loaded. 5 of 5 stars
The charging capability via dock I find less than optimal, too cumbersome. Decisive is the battery life for me, I'm so far surprised positively. Yesterday was not decisive, but I tried too much. The battery was empty in the evening. Well, the adjustment of the automatic shutdown. Between 23.00 clock to 08:00 clock the Callisto switches off.
For my needs of today's test day is much more important. I have Callisto from 11:00 clock (battery 100%) was added in the flight mode. Reason my Lumia today was always going to Callisto only served as a mere clock ". The battery level is now at 94% ... very good. Now many will cry out for what ne SW if you do not use? As I said, for me phablet users comes the SW is very limited for use. I can use it at any time, then disable Airplane mode ... it does not have a rule though. 5 of 5 stars
Consumption under "full load" I can only guess. If WLAN and data usage is enabled, twice has nachgucken the hour because it vibrates and otherwise a little playing around with it ... the evening is one you need to recharge. That was at the Sony SW bit different, as you can about 1 day longer remain energized.
169 euros it costs on Amazon. How do I find very convenient. Compared to Sony SW or Gear Samsung also priced at an advantage.
The Callisto is exactly what I was looking for: The sole use is awesome, a great backup smart phone for little money. It will mainly serve me as pure clock, as needed, activated at any time from the flight mode.
The SIMCARD incidentally, bought once by Tchibo, 1 year with no monthly costs, incl. Phoneflat, incl. 300 MB data consumption high speed.
