Sooo... how does an Ambrose Spanish leather strop look after almost 20k passes? Pretty darn good! 
I have been using one of these at home since the end of June. I wanted to wait on giving a full review until I could give it a real workout. The first week I used it I was already impressed with it. After all the use I have put on it, I can pretty much just sum up the rest of the review in one word: amazing!
Now the strop that I bought was an irregular (see here) but regardless, the quality of the leather and the hardware was excellent. My "fix" was just to put a vintage hanger on it. I was skeptical of the cotton at first as it felt light and really zippy; really not what I was used to compared with the vintage canvas strops (such as Hess Hair, Dubl Duck Satinedge, Kanayama etc.) However, in use, it works great. It certainly kicks up an edge as well as any of those other ones. Mine initially came with a 2" wide one, but I have since tried a 2.5" version and like it even more!
The leather has a interesting feel to it; you'll probably find yourself stroking it often.
I like a strop with fast action like cordovan. Now this isn't as fast as that, but provides just enough draw to give you better feedback. Jose didn't advertise being able to use the back with paste, but I am happy to say the backside provides an excellent surface. You could even use it without paste as the slight texture it has should make it a good "sharpening" side. What I found happens is the little nooks and crannies do a great job filling up and holding the paste allowing the surface of the leather to be unpasted. Hard to explain, probably better to just look at the picture. Basically it allows for a more evenly pasted surface. It freshens up an edge real quick. 
As far as strop care goes, I have applied leftover lather (Cella, a tallow based soap) 3x since the end of June. It hasn't needed anything additional. The surface and finish has proved to be very durable. The leather is still as beautiful as when I first got it. The canvas has not had any issues with fraying or raising a nap. Jose does apply a seam sealer. I am not sure if he just applies it to the cut ends or over the whole thing but regardless, it works great.
I had several strops to compare this one to. Initially I preferred my cordovan strops and felt they gave just a bit of a better edge. Now that the Spanish leather has probably fully broken in and after the lather applications, I'd say they keep an edge equally well. The cordovan has less draw, but as far as performance goes I can't say it holds an advantage anymore! Plus I can use the backside of this as opposed to the cordovan.
In summary, you can't go wrong here. Not only is Jose a stand up guy and a pleasure to deal with, his strops are excellent and a great value. They aren't fancy as some you see with stitching or colored stampings but that isn't what I am into either. I prefer a simple barber end strop.
In fact I like the strop so much, I have sold my other strops and placed an order for a couple others from him, including a cordovan. And get this.... one of those strops I sold... was a Kanayama!
