Review on SING LTD 20Pcs Ferrite Suppressor by Roger Galloway

This product claims to reduce electrical noise in car electronics but it failed to impress me .As a result of my tests, I determined that it made no noticeable difference in the sound quality of my car's audio system. The only positive aspect of this product is its affordable price. Unfortunately it's not worth the hassle of installation as it does not provide any significant improvement. Save your money and look for a better solution to reduce electrical interference in your car electronics..
