I go to yard sales all the time, and occasionally I find things that are cheap.  I have found many old TVs and most of the time they are pretty heavy.  Under normal conditions I  would have to go home and get a trailer and hand truck to get the heavy items to my car.  With these straps I  can leave them in the car all the time in case they were needed, and when they are needed my wife and I can put the straps on and carry the items to the car.  They work even better when bringing the items into the house as using a hand truck in the house can be hard.
