So far I am in love with this thing. I replaced the single locking rose licensed on my Ibanez RG270 and I am frankly amazed. No, its not going to perform like a $200.00 Floyd Rose. With that out of the way, I have been using it to play gigs on my RG, and have not gone out of tune very much at all. Yeah, if I grab that thing and shake the hell out of it, it will go out of tune, but wiggling it up and down lightly generally brings it back to within a tiny bit flat or sharp, but not completely unusable. I used to block all my Floyds because they were not useable in a live situation. I am impressed with the quality so far. Generally Chinese made metals are not durable at all. Bolts and nuts strip, stuff bends or breaks. I had an SKS I could drill with my black and decker drill bits years ago. That shouldn't of happened on a firearm. If you tighten things up on the Rose, use a gentle touch. Do not crank down on them. Keep it clean and oiled up good. I am really blown away that these are only $25.00. The trem that came on my RG270 was a piece of junk right out of the box. Putting this trem on it and upgrading the pickups I have a gig worthy guitar I only have $150.00 invested in. Great trem, highly recommend.
