I'm familiar with Tenecor...what do you want to know? In fact, I'm a dealer in Tenecor. The quality is good, but most of the time I use another company locally (www.truvuaquarium.com) as they are a little cheaper for the same quality. I only use Tenecor for bigger sized tanks that need to be shipped as Tenecor will drop ship for me while the local guy will not.
I have a few tenecor tanks and I'm very happy with them. They are a bit high in price but you get what you pay for There are pictures here www.jimmysreef.com if your interested.
