Conversion Kit

I have an original PRESSO which I picked “new” at a thrift store for $5. Everything was included and worked great; however, I came across a ROK video and learned about an available upgrade kit. Everything fitted like a glove. My PRESSO is as good as new ROK. Pressure has improved, levers are easier to operate and the machine looks so much better. Absolutely worth every penny. I now want to get a ROK grinder.

Nice upgrade works much better then the first generation I have been rokin for the launch best off grid espresso machine I have used

Definitely worth the money. It increases heat retention and reduces the force required for the same pressure

The conversion kit itself works pretty well. I’ve been able to produce good shots with very fresh beans and proper tamping. Great taste and nice crema. Would give 5 stars but you guys need to ditch OnTrac. Literally the worst shipping company I’ve ever dealt with. Among other issues with OnTrac, they lied about needing a gate access code, were hard to deal with, and the driver threw the package 20 feet across my porch. Use a real shipping company like UPS or FedEx. I’m not likely to buy more products from you simply because of the shipping company being complete garbage.

I ordered the conversion kit because i didn't think i was getting enough pressure (even with super finely grinded beans!) in my pulls. I had read reviews that said the calcium deposits made taking the old cylinder out difficult but for me, it was very easy. I mention that because when i installed the new cylinder, i found i was getting only the same amount of pressure or maybe less. Is there a way i can trade in the main body of the rok GC for a new one? Any other suggestions to get more pressure? There's very little resistance when i pull shots.
