In my experience on EMS syncronica, this 18g Baristapro basket outperforms the stock EMS basket and 18g BoB by BIT. It does require a bit finer grind. Gives more stable result. The "nano" layer works great first month than it began degrade. I am just a home espresso user but I can taste difference with this basket. :)
Great basket, really improves expresso
I had issues with my order (wrong part sent, cracked shot glass) but the team responded quickly and sorted it all out without any fuss. Prices were comparable to other companies, but their customer service is what has separated Caffewerks from the pack.
