Review on Logitech G305 Lightspeed: The Ultimate Wireless Gaming Mouse by Ada Fedorowicz ᠌

Slippery - if you take it with dry hands (after washing and wiping, for example), it is simply impossible to hold it. Shape - the sides of the mouse converge downwards, because of this, the grip becomes even less reliable. The side buttons are small, to press, you need to make an effort. In general, they are pressed easily, but because of the small area they simply miss the fingertip, remaining in place. Also, with an incomplete grip, when the fingers lie approximately in the middle of the length of the main keys, the thumb barely reaches the edge of the nearest button. If you put your palm completely, the thumb completely covers the nearest button, not reaching the far one. How Logitech managed to do this is unclear to me. The side buttons had to be moved to the side of the hand by at least a centimeter and made at least twice as wide. The wheel is moderately tight, the cutoffs are more or less clear, its drawback is that the force of holding the button in the pressed position is too great. It's hard to explain, but the G403 had the same pressing force, but the button's membrane, after clicking, was not as eager to return to its original position, so it took less effort to keep the button pressed than to press it. Not so with the G305, the finger quickly gets tired of holding the wheel down.
