I have used the Rico mouthpieces for probably 30 years now because they are of exceptional quality and value for the money. Designed by Arnold Brillhart, they are very free blowing with accurate intonation, are very responsive in both the high and low notes and produce superb tonal harmonics allowing you to balance the sound of any sax. The Metalites really do sound like metal mouthpiecs due to the design of the raised internal baffle and the type of plastic used. At a fraction of the cost of top branded mouthpieces they give you the opportunity to experiment with wider tip openings until your embouchure matures while you think about the sound you want. I continue to use them on my altos and soprano saxes and have Metalite and Graftonite models for the whole range of saxes including using then as standbys for my tenors and baritone. If you buy a new sax and find the stock mouthpiece uncomfortable or you need to finally upgrade to a more open tip mouthpiece then simply buy a Rico, if only to test what works for you. They are 5th to a 10th of the price of most brands.
