Utterly transformative! How is it possible that changing from a 2-hole tip to a 1-hole tip could make such a difference? After 3 weeks of trying every technique, watching James Hoffman and Lance Hedrick and Coffee Kev's videos a hundred times over, I was still completely unable to get anything like acceptable foamed milk. Bought this in desperation, fitted it and the first two flat whites I made were just perfect. I'm completely flabbergasted. If you're buying a Gaggia Classic Pro, just buy this tip. You'll be so glad you did. This old man feels slightly ridiculous that such a simple thing has made me so happy!

I bought an OPV kit and “The One”. I had hopes for the OPV, The One was more of a whim. Both were immediate successes with clear improvements.

"The One" really does make a difference, especially for someone new to steaming milk, like myself. I noticed two differences: 1) the machine is now able to provide enough steam to fully whirl and texture the microfoam for the whole time until beyond when the jug is feeling hot, unlike with the original two hole tip which would often run out of pressure. And 2) the whirl or vortex that it provides is much better than with the two hole steam tip...it can really get spinning! I'm sure experienced users can get good results with the two hole; my results were mediocre with that. But upgrading to "The One" tip was a noticeable change for me, and steaming milk is now easy rather than something frustrating.

I was really struggling in steaming milk before buying this as a new gaggia user. I watched all of the popular guides in how to steam milk and nothing worked. I installed this and was able to steam milk perfectly the first time.

Never tried the original, swapped it out straight away. Makes perfect micro foam so 5 stars.

That thing is awesome! Wasn't too sure if I should buy it initially, but figured I might aswell, with all the money I've spent on my machine already. Not a single regret. It's so much easier to get a good swirl going in the milk, since the steam obviously isn't pushing in two directions. Takes a second longer to heat it, but not much. I actually prefer it this way, as it allows for some more margin of error. It's totally idiot proof now.

The One tip is much better to oem tip, I am learning to latte art and now with this tip I can get much better results than the oem tip, totally recommended!!

This little guy is a massive upgrade. I love it and would never dream of using the OEM attachment ever again. [Soc} Thanks Sean - we love it too. It took a lot of time and effort to perfect, but it does make a huge difference to steaming power for most people - especially when you have PID controlled steam.

Just steamed my first pitcher. Wow! The difference is amazing. I don't even need to turn on full. Steamed almond milk with more forth than I've ever had. Excited to dial the steaming in.

This tip increased the quality of the foam very much so that I can understand why I failed latte art before.

This steam tip should come stock on all GCP. Drastic difference with two-hole tip. Gives full control and virtually infinite steam.

Get this steam tip! The steam power has increased and the quality of the microfoam is so much better than the two hole tip Great update well worth it
