I have the orange 250Hz version with display. I maxed out at 12,700 when I used to use it daily (for about 2 weeks!), and just picking it up again am on 12,000. I'll leave it on my desk and see if I can hit 13k over the next couple of weeks.
The only problem I find with it is that it gives me blisters and the band slides off it in use.
