They worked fine on my Chinese Strat Standard. I didn't hear any lag or noise. The range also seemed good. I walked through 3 rooms with walls in between (probably 40ft) without losing reception. I only play at home so they would be perfect for my needs other than my other guitars. I mainly play two Ibanez (S and SA series) and the transmitter will not fit into the swiveling "hinge" connector on the guitar face before the connector is fully seated. I've attached a photo to better understand the problem.
