I got my Rancilio Bottomless filter today and tried it out right away. I put in double shot basket (18g) since I didn't want to do a triple shot. The basket fit just fine into the porta filter and into the Silvia. Got a great shot out of it.

Overall I think it's a great Bottemless filter. The metal around the portafilter feels solid and looks great. The handle is good but there area where you find the Rancilio logo has some plastic edges that stick out and feel a little sharp, but not a deal breaker. I think if you want to get a bottomless portafilter, highly recommend getting this one to improve your espresso game.

El portafiltro desnudo es muy adecuado para mi máquina Rancilio Silvia V3, sin embargo, el recipiente que se incluye deja mucho que desear: es un recipiente que no trae la especificación del gramaje que soporta grabado al costado del mismo. Es un recipiente de 21 gramos que no funciona bien con menos de 20 gramos.

I'll give this 5 stars based on construction. This one shipped with the filter basket as well. It came quickly and was sold by Kanen Coffee LLC through amazon.

I'm still figuring out the world of espresso makers. I have a Gaggia Classic and the only bottomless portafilter that I've found so far for my machine isn't made by the manufacturer. I thought I'd try the Rancilio version when I read that it was very well made. Indeed, this looks and feels very well made. Holding this portafilter and my Gaggia portafilter I must admit that I liked the Rancilio version better. Holding the two filters sided by side the Rancilio basket rim looks more robust and it looks a bit larger than the Gaggia version. In the picture I think the Rancillio basket looks a bit smaller only because the spout on the bottom of the Gaggia filter raises it up closer to the camera. Note the difference in the angle of the tabs on the side of the filters relative to the handle.

Since I thought the connection was fairly standard so I decided to give the Rancilio a try. The tab angle would have been no problem if it fit otherwise--I wouldn't mind that much if the handle didn't stick out at the same angle. Well--it doesn't fit the Gaggia Classic because the diameter is slightly too large.

I got this while it had a discount for around $93.00 with shipping included. I really like how it is lightweight and can hold all the basket sizes I had as stock of my RSPROX. It came a lot sooner than I expected too. If purchasing for an RSPRO/RSPROX, make sure you turn this bottomless portafilter a bit tighter than the other one with a double spout so that you can really seal it in. Otherwise, water will come out due to a weak seal.

As one would hope, this bottomless portafilter for the Rancilio Silvia, indeed works with the Rancilio Silvia. Although the handle doesn't look exactly like the one on the original spouted handle it does match the machine well. The triple basket is not worth your time using and I just bought a VST basket and it fits great and makes good espresso.
