I took delivery of my mbw-150 this morning and must say that i am very impressed with the quality and finish of the materials used (not surprising for sony ericcson).
While the watch is slightly larger than i anticipated it is not massivly oversized and fits on my wrist snugly (now i have removed 2 links).
It paired with my phone (also sony ericsson) with no problems at all and although the book says that the link range is reduced when solid objects are blocking the signal i find i can go 1 or 2 rooms away from my phone (roughly 10-14 metres) without dropping the conection.
The call display feature works like a dream and it instanlty shows you either the name (if you have a name for the caller in your phonebook) or the number of the person calling.
The music player function also works without a hitch although the phone i have it connected to doesnt have track ID compatibility and the track skip buttons can also be used to raise or lower the volume of the music from your phone (dependant on the length of time you press them for).
The menu is very easy to use and is explained well in the handbook (one small issue is that the user guide shows different icons to the actual phone but the icons are very self explanatory).
The watch took 2 hours to show a full charge but i suspect this is like any new product and future charges will take half this time. As a side note it charges from an attachment that fits into a standard sony ericsson charger and both the charger and attatchment come supplied with the watch.
The watch has a digital date and also shows the time in digital (good for night time) at the click of a button but reverts back to a blank display after a few seconds.
The only things i was slightly dissapointed to find lacking were an alarm and stopwatch function as i would have thought these could have been squeezed into the product without having to sacrifice size or weight. Personally i dont use a watch alarm and the times i need a stopwatch per year could be counted on one hand so these aren't major complaints.
Overall a very good product, if i have any more information to add after i have lived with it for a while longer i will post another review.
