My istick power 50 is only a few weeks old and I was able to lock the adjustment buttons but for some reason it just stopped working. I'm continuously pressing the up and down buttons for 2 seconds and then trying it for 3 seconds and four and five and six seconds and more but none of the times I tried it did it display the lock message. I did try to increase and decrease the wattage after each try and it did increase and decrease so it's not a matter of it just not showing the word lock. I'm worried I won't be able to find this site or my forum again after this entry so if anyone knows how to fix this problem, please email me at: removed private e-mail Thank you. John
