Question about Logitech Lift

I find this question justified. One Lift for CHF 70.40 and one Lift for Business for CHF 74.30.

The only difference seems to be the wireless adapter.
The normal one is compatible with the previously common Unifying receiver, the business version uses the new Bolt adapter instead, which offers additional advantages in remote maintenance. So it's interesting for large companies, but it doesn't matter for home use. Moreover, the two are not compatible with each other.
When connecting with Bluetooth, it doesn't matter.

I don't know what you mean by business variant.

The Lift is for smaller hands than the other one from Logitech.

I don't know which is the business version, but the Logitech Lift is worth the money. You first have to get used to this posture of the mouse, but after 2-3 days the effect already comes. The mouse relieves the muscle in the upper arm and my shoulder pain is finally gone after more than 2 years. In addition, the mouse can be registered and used on 3 different devices, which for me are the company notebook, private PC and mobile phone. I can only recommend it.
