Worst off brand blocks

The non lego brands I've tried!

The model above didn't fit and the center was just a large cutout piece.

This tyco phone was not able to be taken apart

rite aid had the above models that I did enjoy but clutch power and fit weren't good.  I was going to try making a train car with a dome but the windows would need glued in place.

These generic bricks didn't mesh with real legos well

I couldn't believe how light these pieces were and clutch power wasn't there!  Same below 3 pics

You sure can see the quality of lego vs. The above sets
