unrelated, does bluetooth work well with the MX Master 3s?

I use the 2S and the 3 over Bluetooth (Windows 10 and Linux (Pipewire/pulseaudio)) and they generally work well. But on Linux I sometimes get lagging sound on my bt headphones, when I use the mouse heavily, and on Windows I get a rubber band effect on the mouse when I use a headset for calls, but not music. ymmv

I have been using a MX Master 3 (non-S), and an MX Anywhere 2S for the past few years on a daily basis, on multiple devices (Windows, MacOS and Linux). Bluetooth has been working flawlessly every time. I don't think I have ever used the unifying receiver dongle.

This is why I don't understand the DongleHider+ here. If you don't want the dongle, why not just connect via Bluetooth?

In my experience you can't use more than 3 bluetooth devices at the same time.

Currently I have a headset, a mouse and a keyboard. To add anything else I would have to remove something else.

Last year I've built a simple 3-key macro pad using an esp32 connected via bluetooth. When I tried to use 4 devices at the same time I had a pretty bed time.

I don't know this for sure, but I suspect if you have someone else sitting by you side and also using 3 devices I think the interference could cause some strange behaviour.

Battery life and responsiveness.

Mine has worked flawlessly for about a year. A few months ago, it’s become horribly janky and I can’t figure out why.

Tried different MX Master 3S units and different computers in different rooms but it’s just janky everywhere now. (Bluetooth keyboards, too.)

It doesn't work well anywhere due to BT protocol lag and low refresh rate.

Correct. There's a reason every wireless gaming mouse uses a custom protocol + dongle.
