I have both models and have not yet noticed any difference.

The mouse is not compatible with the Logitech Unifying receiver. It is specifically designed to work with the Logi Bolt USB receiver or via Bluetooth Low Energy, and Logi Bolt devices are not compatible with Unifying devices.

The main difference between the "Logitech Signature M650" and the "Logitech Signature M650 L" (which is often referred to as "M") lies in the following aspects: ## Size - The "Logitech Signature M650" comes in a medium size, while the "Logitech Signature M650 L" offers a larger size to accommodate different hand sizes. ## Dimensions - The medium size measures approximately 108.2 mm in height, 61 mm in width and 38.8 mm in depth, with a weight of approximately 101.4 g. - The large size measures approximately 118.7 mm in height, 66.2 mm in width and 42 mm in depth, with a weight of approximately 115.4 g. ## Comfort and ergonomics - Both models have a contoured shape, a soft thumb area and rubber grips on the sides, but the larger version offers more space for larger hands. ## Availability of left-handed versions - The "Logitech Signature M650 for Business" is also available in a left-handed version, which is not the case with the standard version. These differences allow the mouse to be better adapted to the individual needs and hand sizes of users.

No, the Logitech Signature M650 L mouse cannot be connected to a Unifying USB receiver. The mouse is specifically designed for the Logi Bolt USB receiver or Bluetooth Low Energy and is not compatible with Unifying USB receivers. Logi Bolt devices and Unifying devices are not compatible with each other.

No, as shown in the photo, classic USB A

Goes with Bluetooth

Since I have a Windows notebook, I cannot answer this question.

It has a slight resistance with each "line jump".

No, you can't.

Hello, the M650 L is also compatible with Windows and MacOS. I have tested it with both operating systems and it works perfectly

Hello, the Logitech m650 Mouse Business GR is basically the same, the only difference is the colour and packaging, and that it is advertised for business use.
