The absolute worst thing I ever bought was the WBTS teachings. I owned it for about 35 years mainly because it advertised it came with a lifetime guaranty. I tried to read the directions but they were strange and required too many steps. I called their help desk but everytime I got the same responses, that I was reading too much into it or they never meant it that way.. I inquired about the lifetime warranty to which they said it has been revised a few times, apparently once in 1914, again in 1925 and most recently 1975. I tried and tried to recieve compensation for my "lost" time trying to figure this thing out, but everytime I call now all I get is recorded messages.
Oh well, live and learn I guess. I recently had a garage sale and tried to give it away but sadly no takers. apparently, this faulty mechanism has been found out. so.. on the shelf it goes with my get rich quick at real estate tapes,ostridge rangling opportunity info and Ginsu knive collection.
Buyers beware!
