I just wanted to mention, I don't find the auto-shutoff to be a pan at all. MY scale is the AWS-100. It shuts of after a minute of inactivity. When I mix everything is out and setup and ready to go, so even if it does turn off between ingredients, so what. I just take the bottle off, turn the scale on, place bottle back on, and finally tare the scale again. In the future when I start making bigger batches, I'll have to look for something with higher capacity and the one you selected looks perfect!
BTW, I also bought these : TOOGOO(R) Stainless Steel Luer Lock Dispensing Needle Tip, 12 Gauge, 2.05mm ID x 2.8mm OD, 1" Length (Pack of 6)
It makes working with VG, and VG based nicotine easy, to me even much easier than using pipettes.
