Query: One Major Flaw - Impossible tuning for Computer Sleep/Standby

I really wanted to like this product. It is a great idea and the design is almost perfect. The major problem with the design is a single $0.20 trimmer pot ( variable resistor ) that is used to set when your device is ON versus OFF. It is VERY hard to set. My computer in Sleep mode consumes 50W and in normal ON mode consumes 100W. Tuning the strip to recognize the difference between the two power states required about 1/10 of a degree turn - hard to do. What is worse is that even after I got it working once, temperature variation in the circuit would cause it to stop working the next day. For many applications ( for example, computer hibernate=5W, vs ON=100W ) this device works just fine. I can't recommend it for computer Standby however. If they would improve the circuit with a multi-turn pot, it would probably work great. I might try this myself after the warranty period is over. Should have been a great "Green" product, sigh....
