Shape

In terms of shape, the Atlantis is often likened to the Endgame Gear XM1r. While some similarities are present, the shape of the Atlantis is different enough to where the two mice don't feel particularly similar in hand. Much like on the XM1r, the hump is positioned slightly towards the back, but doesn't slope down quite as aggressively, and the hump itself is somewhat flatter, yet wider horizontally. While the back flares out in a similar fashion as on the XM1r, the sides integrate into the back differently due to being slightly slanted like this: \ /. Essentially, the Atlantis gets thinner towards the bottom at the sides, along with the sides curving inwards horizontally. As a result, when looking at the Atlantis from the top, it looks much wider than when looking at the bottom. Even though the Atlantis has comfort grooves on the main buttons, they are very subtle, especially when compared to the deeper grooves found on the Pulsar X2.


As for grip styles, I'd say the Atlantis mostly suits claw and fingertip grip. It is a medium-sized to large mouse with a moderately 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 Atlantis very comfortable in claw grip.

Dimensions

This table includes the dimensions of the LAMZU Atlantis and several other ambidextrous 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.
