Moisture Mirrors have one thing you will not find with another piece of gin equipment...100% trade-in value when you upgrade. Since 2002, when the Mirror 2 was introduced, Samuel Jackson has offered gins 100% of what they paid for their existing Mirror to upgrade to a newer model. This applies to all current models and any upgrade path you choose. So, whether you're upgrading from a Mirror I to a Mirror 2X or from a Mirror 2X to a Mirror 4X, you only pay the difference in price between the models. With a Moisture Mirror you'll never loose a penny of your investment, so deciding which model best fits your gin is made much easier and worry free!
