Great Product

Very sturdy construction with high quality materials. Does exactly what it claims to with little to no operational troubles. I have used this in the past and decided to purchase it once again. One can say it is a bit pricey compared to other manufacturers, but with years of use and not a single complaint, it is definitely worth the money.
