There's a serious design fault with this ziplighter sized timepiece: the four setting buttons on the reverse are all but indecipherable (being black rubber on black rubber)- which means that unless you are particularly adept at things digital, or have the memory of an elephant, or will for evermore have the chinglish instruction booklet to hand, something as simple as setting the alarm is likely to be a very frustrating exercise indeed. Note also: batteries are the type used in watches etc - NOT double or triple A's; which will be a hassle and a half to replace 'on the road' unless you got a spare tucked away somewhere. All'n all very so so...
