I received a box of this stuff from Chris a few days ago and let me tell you guys it is beautiful stuff. He's a great guy to deal with as well! The glue joints can be found but that's only because of the little "stones" in the material starting and stopping. The glue he uses is colored to match so you don't see the glue itself at all. The material turns pretty much like acrylic. I've been wet sanding it from 320 to 800 then using plastic polish and it shines beautifully.
At $10/stick the price is fairly reasonable in my opinion. Think of the price of 4' of colored acrylic rod in 1-1/2" diameter....More than $40.
Here's the first call I turned from the stock Chris sent me.

The seams are barely visible in the blue at all. They do show up on the white, but only if you hold it up to a light! They do not show up enough to detract from the call in any way. The darker colors that don't allow light through like the white does would be even better.
