Definitely bigger than what I anticipated after upgrading from a small magnum. This one has no trouble staying in place, and sits in comfortably, allowing to use it as a plug. The huge surface area also allows to use more power than you usually would, making it well suited for a tri-phase setup. My one point of contention is that I would have preferred it to be stumpier, about 3cm shorter in total insertable length, and maybe with a base that could be half-inserted. Still, this is definitely an electrode I do not regret buying as it is pretty close to ideal.
