Shape

If you already know the shape of the Razer Basilisk then you know the shape of the DM5 Blink as well. That isn't necessarily a bad thing, however, as the Basilisk is one of the better right-handed ergonomic shapes out there. Notable is the lack of the Basilisk's thumb rest on the DM5 Blink. This is both a good and a bad thing. It's good for those who disliked the thumb rest or simply found it to be rather restrictive in terms of how the mouse can be gripped. Yet its absence creates an issue with the original design: With the thumb rest, the thumb is supposed to sit slightly higher, which makes it easy enough to reach the side buttons. On the DM5 Blink, the side buttons sit at the same height as on the Basilisk, but the thumb naturally sits lower, which can make reaching them difficult. In the same vein, the dedicated sniper button too sits in the same place as on the Basilisk, but there, an optional piece with a longer stem was available to make it easier to reach. This piece is again missing on the DM5 Blink, which makes it rather cumbersome to reach the sniper button, especially when one wants to use it for its intended purpose; that is, as a button that is continously pressed for fine-aiming adjustments.


These minor ergonomic quibbles aside, the shape itself is just as good as on the Basilisk. As expected from an ergonomic design, the left side is raised all the way, while the right side sits noticeably lower, especially towards the front. The hump is placed right in the middle, but slopes down in an asymmetrical way: On the left side, it gets "cut off" at the front due to this side being raised, while it slopes down organically towards the back. Across the width, the hump isn't tapered but rather flat, which, combined with the shorter length, makes it very comfortable to rest one's palm there, more so than on many other ergonomic designs. Much like on the Basilisk only the left button has a fairly deep comfort groove, while the right button is slightly convex.


As for grip style, I'd say the DM5 Blink can be used in all three main grip styles (palm, claw, and fingertip), although it's most suited for palm and claw grip. It's a medium-sized, but fairly tall mouse, and on the shorter side of things. For reference, my hand size is 19x10 cm, and the DM5 Blink feels very comfortable in claw grip.

Dimensions

This table includes the dimensions of the Dream Machines DM5 Blink 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.
