This was indeed just bolt on. Just be advised that if you're coming from a stock wand, you'll have to raise your Gaggia on feetor something else so the jug can fit under it. This is my first time using a wand and trying to make microfoam: I didn't realise that there's a little bit of technique! I'm still learning how to create bubbles and vortex, but I'm very happy with the wand so far. Shipping was fairly quick to Australia. They used APG eCommerce for tracking, which apparentlyis affiliated or owned by Australia Post (first time I've encountered this). Customer support was okay. My email wasn't replied to but they replied to me on Messenger. I'll definitely be a customer again if I need anything.
