Shape

Anyone knowing the shape of the Xlite V3 series is also familiar with the shape of the F01. The only difference lies in the size, as the F01 is smaller than the Medium ("Size 2") variant of the Xlite V3, and lands somewhere between Size 2 and 1, amounting to a "Size 1.5" if you will. The scroll wheel is the same as the one found on the Xlite V3 eS, though positioned slightly more towards the back relative to the front. Of note are obviously the large and mostly rectangular holes found across the bottom, back, and part of the main buttons on the F01. While the finger contact points remain solid, those using a full palm grip may feel irritated given how the holes are large enough that one's metacarpophalangeal joints fit in neatly. Accordingly, the F01 lends itself better for claw grip.


As for grip styles, I'd say the F01 is generally suited for claw and to a lesser degree palm grip. It is a medium-sized mouse with a fairly pronounced hump, which should make it generally suit most hand sizes. For reference, my hands are 19 cm long and 10 cm wide, and I found the F01 comfortable in claw grip.

Dimensions

This table includes the dimensions of the Pulsar Feinmann F01 and several other right-handed ergonomic mice. "Front height" denotes the distance between the base and main buttons. Measurements with two decimals have been taken with a caliper, while those with one decimal have been taken with a ruler. For a full list of all measurements taken, please refer to this sheet compiled by an esteemed community member.
