It is a vibrato that I use for almost 5 years. I had to order another one because the old had passed away. It was already mounted on the guitar that my teacher gave me. Before making the core 15 good years have passed. Difficult to find, it is much cheaper qd even if we do come from the USA (about 130 euros, including postage). Installation is quick, convenient and the setting of the more childish ... not ask the luthier to make a site for installation. Performance level is in the spirit of Floyd but I find that less powerful vibrato licensed floyd ... That is his obligation to the agreement leaves something to be desired, but even if its use provides qd. on the other hand is much softer than a floyd, and it can be confusing ... We sometimes feel a toy in the hands and can not dare to make certain effects in the handling ... That said, it remains a very good compromise for those who want a vibrato, quite correctly, at a price well accessible without paying a huge price for installation ... And then, again, the setting is childish . For we can read the manual, you can do it alone. I certainly would do if the choice had to buy another, but I will type more towards higher-end models
