I have more than one XS. I bought my first, used, in 2013 (I think). For a while I didn't use it because I hd more trust in my CoagSense. I'm using the XS much more often than the Coag-Sense - the Coag-Sense is an occasional test to compare the two results.
Roche Tech Support is really good - partially because they have to be. You shouldn't have slipshod support for a device that helps you make life or death decisions (are you hearing this Coagusense?). I've found Roche support to be extremely good.
Last year, I got an XS Professional meter. It's an interesting meter - more meter than I actually need. It has a good color display and more options than my lowly XS. It was made for hospitals - stores a LOT of tests. Roche support helped me to set it up more as a personal meter than as one designed to be used by multiple operators and hundreds of different patients. It has many of the features that I think the new Roche meter has.
This meter is kind of like a large earthmoving machine when all I really need is a shovel. I rarely use it.
For me, my 'new' (bought for about $30) XS is pretty much all I need.
