Well, I've had mine for 4 months now, just wish I'd taken the plunge before because it's really opened up a lot of really creative work to me.
As a ringflash, I use it for fashion and some glamour work, It's the ideal lighting effect for when gentle, outwardly radiating shadows are wanted and none of the small clip on ones can do anything near what the Lencarta ringflash does. Also it has plenty of power, so can even be used in bright sunlight.
Speaking of bright sunlight, it's the ideal fill flash for portrait groups, weddings for example) because it has 10 times the power of any hotshoe flashgun. I've got the optional extras too, a 5 metre extension cable and the new ringflash diffuser, which makes it even easier to use and more versatile.
The other thing I bought was one of the Safari 600 heads. The pack can take either 1 or 2 heads or 1 head and a ringflash and the head makes it easy to have studio flash outdoors, with all the power and the creative light shaping tools of ordinary studio flash heads. It has enough power to completely overwhelm the sun.
It's a first class bit of kit at the fraction of the cost of Bowens, Elinchrom or Profoto and it gives far more flashes from a charged battery too. I always get at least 1100 flashes from a 3 hour charge and sometimes over 1300 (more in hot weather).
Whoever did that Practical Photography review hasn't got a clue. This is the best thing I've ever bought.
