The Harvey Crown Vs Harvey TwinTec S4

When it comes to deciding between the Harvey Crown Vs Harvey TwinTec S4 - it can be a tough decision - especially if you're on a budget. The Harvey Crown was created over 10 year ago - meaning its model and efficiency is dated. The system itself is considered a budget system and entry level product. The TwinTec S4 is premium and exclusive product which is one of Harvey's latest models. This system is build to last and even comes with a 10 year warranty on parts to prove this.
