Bluetooth mouse too fast

I recently got a Bluetooth key and mouse pair to clean up my desk. The mouse, I found was way too fast compared to the wired one. After some  research I found this program (xinput) to be useful in this case.

My input devices:

First I listed my input devices:

user@box:$ xinput --list --short

⎡ Virtual core pointer id=2 [master pointer (3)]

⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]

⎜ ↳ Wacom ISDv4 E2 Finger touch id=10 [slave pointer (2)]

⎜ ↳ SynPS/2 Synaptics TouchPad id=12 [slave pointer (2)]

⎜ ↳ TPPS/2 IBM TrackPoint id=13 [slave pointer (2)]

⎜ ↳ Logitech Logitech USB Optical Mouse id=15 [slave pointer (2)]

⎜ ↳ Dell BT Mouse id=18 [slave pointer (2)]

⎜ ↳ Dell BT Keyboard id=19 [slave pointer (2)]

⎣ Virtual core keyboard id=3 [master keyboard (2)]

↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]

↳ Power Button id=6 [slave keyboard (3)]

↳ Video Bus id=7 [slave keyboard (3)]

↳ Sleep Button id=8 [slave keyboard (3)]

↳ ThinkPad Extra Buttons id=14 [slave keyboard (3)]

↳ BTC USB Multimedia Keyboard id=16 [slave keyboard (3)]

↳ BTC USB Multimedia Keyboard id=17 [slave keyboard (3)]

Then I checked the properties for my mouse:

user@box:$ xinput --list-props "Dell BT Mouse"

Device 'Dell BT Mouse':

And then I adjusted the velocity scaling:

user@box:$xinput --set-float-prop "Dell BT Mouse" 252 1.0
