I find it pretty much superb in every aspect, it's only possible "fault" being that it's so light weight that getting it to sit correctly in a wind can be a pain.
It doesn't give ftlbs automatically (unless using the PC interface) but that has never bothered me, it shows the Velocity = max - min - ave - max spread & SD.
I'll already know the max velocity I can have for the pellet to stay safely under 12fpe along with the velocity at 11.5fpe which is where I like to set them, so I'm just after the consistency within that range.
I've used it with air, FAC air, Rimfire, Centrefire & even a Shotgun, and as the memory holds 9 strings of 99 shots it's ideal to check multiple rifles or to compare 9 ammo types through the same rifle.
With the interface you can either print the results or save them on PC.
