It's rare that it doesn't take a dozen hours before you've figured out how to get consistently good prints - regardless of the printer - although the UM2 often works fine right out of the box. Anyway that part in that picture is really really tiny - can barely see it but I think it looks like maybe it stopped extruding? I mean most of it looks fine I think. Would be very helpful to zoom in a bit first.
Anyway there are lots of things that can cause that - most common are having too many retractions or printing too fast such that the feeder grinds up the filament - check that out by opening the feeder, heating up the nozzle to 150C and pulling it out a bit and inspecting the part in the feeder. Also printing too hot can cook the filament into gunk - but this is very unlikely with PLA. Also you might have dust/dirt/wood particles (from feeder getting chewed up? examine and look for that also) getting into the nozzle and causing a clog.
Your feeder tension might be too light. Also try printing 30% slower and 10C hotter - what are your settings for speed, layer height and temp?

I too fell victim to the good reviews on the website and low prices. I have the clogging issue as well, but my main issue is that it won't feed properly in my UMO. I have gotten few successful prints with this material, but those that did succeed were really small. Most of the 25 or so prints I attempted ended up looking like this
