What do you guys think about the ROK Presso machines?
http://www.rokkitchentools.com/


Although I don't plan to buy them, I'm a little intrigued by these manually operated machines.
While I was shopping for a grinder, I learned about the HAG One, the currently manually operated grinder with a huge conical burr and zero grind retention.
Then a friend asked me about Aeropress, which led me to find out about the Presso ROK also.


Have any of you used them?
I don't know if it is capable of generating high enough pressure but if it can, it seems it would make a very interesting combo with the HAG one grinder.

The last incarnation of this machine was sold in the US by All Clad.  I have one.  There are two issues with it:

  1. There are large air spaces in the piston which makes it difficult to get the pressure required for a good shot of espresso.  I have worked around this with a technique of pumping the levers up and down.  Jim Schulman has a mod which fixes this. I believe it is on Home Barista.  I was going to do the mod but have yet to do it as I am a bit scared of the machine which brings us to the second issue.

  2. The handles have been known to break causing the machine to tip and scald the user.

The new folks claim to have improved the metal to make it stronger.  I have no idea if they addressed the issue which made Jim's mod necessary.

If they have successfully fixed the flaws, it is a fun toy and can make a decent shot of espresso but is an effort with the preheating.  

If you get one, be careful.

I believe I've posted about this before, but I should again.

I admit that I don't own one of these personally, but the design makes me feel quite squeamish. With the piston is at the top of its stroke,
There isn't much in the way that is stabilizing the machine. It only looks like it gets progressively more stable as the stroke progresses.

I also think that one shouldn't have to modify a product just to make it useable. That's just bad engineering on their part. Perhaps they've
rectified it, but I'm doubtful.

Like what PJK said, its a toy. I think your money would be better spent on a proper conventional lever machine. If you do decide to buy one,
just be really careful. Having a cylinder of very hot water tip over and scald you is a very real possibility with this machine.

 
Garbage In, Garbage Out, for every step of the process. From Beans to grinder, grounds to machine, coffee to cup.

In the past, the above type of "Oh, I have a question about the Rok" post has been done more than once by people trying to sell them on eBay, or somesuch.  Our opinions on them vary from Qualin's "It's a fun toy, but an actual espresso machine is better" to It's hardly an espresso machine at all...  You use your kettle (Not included) to heat the water. Use your grinder (Not included) to grind the beans, then you use your Garlic press (The one item that is included) to make a mess. If you're lucky you end up with a decent espresso after much practice.  It's probably better than nothing. I can imagine it being great to have if you're living out of your car and have a cigarette-plug immersion heater for your water and a hand-operated grinder...  But if you have access to any expresso machines that actually help you to make espresso in any way (Even just a heater, if no pump), you'll use it over the Rok.
It's pretty shiney and if you have 2 of them they'd make good book-ends on a shelf in a coffee shop.
