In test he uses 120mm version, it's Weight just 9,0kg, but holds plenty of abuse. 140mm (Jaw width) much beefier and weights 16kg -I have one (140mm) on swivel base - I know, that I am talking about.
Of course, there are many very good vises, bit imo, HEUER in price\performance one from the best, if not the best. At least in Europe. I like RIDGID Matador too, but HEUER little better.
I like very old model of Heuer front with round bar from 1939, I restored and sell two of them! And yes, they have ball bearing in spindle! And double start thread, in 1939! Sadly, that they changed design. On ball bearing its sooo smooth.
