IMPORTANT QUESTION!
I have a treadmill that I bought last year from Wal-Mart and I have not had any trouble with it making the lights flicker... I absolutely love my treadmill, it is just too hot to go walking outside! I can come home from work, make the kids play in their room, and take 20 minutes to myself and walk the treadmill! I will put my favorite music CD in the CD player and turn it up loud and just walk....... lol
