I received this in the mail today and it is a "very" nice unit. Is is smooth but a bit seemd little stiff (not jerky) out of the box. It does not have a "thumb" wheel like the Starret which I also have in this size. I tried the Starret without using the thumb wheel and it was identical to the this unit in effort required. So a thumb wheel will reduce effort to move.  I tried both the Starret and this unit on a known object and got exactlly the same readings as one would expect. The Silver numerals on the black back ground are as easy to read as the black on white numerals on the Starret even in dim light. This unit has a solid metal dial case (Starret has plastic) which I really like and seems to be a touch smaller in over all dimensions than the Starret. The unit comes in an attractive dark grey plastic case with a positive slide latch mechanism. The Starret comes in a red plastic box wih a simple "pop" type latch. Additionally this unit has space in the standard plastic case that is supplied for a T-Bar depth base. You must upgrade to the optional case if you want that for the Starret. All in all it is really hard to choose between the two as both are qulity instruments.  Note if you get the T-Bar depth base you need to order part no. 5.60013. It is finished in silver and sized in mm and is approximatley 3 inches long and will fit in the supplied box. Do not order part 5.60086. It is finsihed in black. It will fit the caliper but is too big at 3.35" long to fit in the cuttout in the supplied case!
