Here's a comparison photo with all three.

The Black Knock Off: Slightly heavier than the Cibi. The walls of the glass are twice that of the Cibi. Color ranges from jet black in low light, to a dark green in bright lighting. Also the black only extends down into the drink well and to the mid line of the glass, the bottom being completely clear. The glass edges at the lip are cut flat with sharp 90 degree corners, not rounded over as they are with the Cibi. Size is 1:1 compared to the original, it fits good in the hand and drinks ok aside from that flat edges at the lip of the glass.
Price point: $25.00 for a set of two.
Bottom line: an affordable, if imperfect alternative that is the closest match on the market. Dishwasher safe.
The JoyJolt Carre: Weight is on par with the Cibi. The walls of the glass are comparable to the black , but slightly smaller. The angle aesthetic matches that of the 2049 bottle. The base is off center to the glass itself, which gives it an asymmetric appearance, but surprisingly fits very well in the hand, as the angle of the base gives your thumb a good grip on the glass, while the upper part of the glass above the angle sits comfortably in the web of the thumb. Hard right angle corners it lacks the tapers found on the Cibi. The lip of the glass is nicely rounded over and you never get the feeling that you could cut yourself on it. It sits stable and doesn't give any impression that it would tip over.
Price point: $40.00 for a set of two.
Bottom line: More expensive than the black knock off, but the design aesthetic so closely matches that of the 2049 bottle that it compliments it nicely. Dishwasher safe.
Either are good choices for relatively inexpensive bar ware that matches the Blade Runner aesthetic. Also, you're not likely to be that upset if one breaks or gets chipped. As careful as I am with my Cibi glasses one has gotten chipped and that really stings considering the price point and the difficulty of getting one.
