Does the Nuvinci ever slip? Any comments on the more recent CVTs below?

So far, I only received the OEM pricelist and a SolidWorks model for the Pinion. Have no practical experience with it, except I saw it with my own eyes on the Spezi fair earlier this year (www.spezialradmesse.de)

RE: bicycle CVTs
May Nuvinci prosper, and I believe they are. They make a fine device, easy to retrofit. I guess so, anyway, I haven't tried it. The disadvantage for a bike is the extra weight away from the center of rotation. Is that a bicycle term? I suppose it is not fixed, because the rider moves around a little, but it must be somewhere near the crank. This is probably negligible in a trike.
The range of the Nuvinci is not large, but apparently good enough for the majority of bike owners. I don't have any problems with the 24 speed chain/derailleur drive on my commuter bike, so am not looking to change it. I am just interested in developments. If I ever decide to take a long trip, your trikes look good.
