Update 2/23/11. I contacted the supplier about the missing gauge and they stated that it should have come with a gauge and sent one out immediately. I upgraded my rating to a 5, as the unit is well built and DOES come with gauge.

2/22/11. I haven't installed the unit yet, but on first look it appears to be very well made. No light weight plastic. However, you need to be aware that it does not come with the gauge shown in the photo. You have to order the gauge seperately. Not a big issue unless you are comparing the price of this to other units that do include the gauge. I would have given the product a 4 or 5 based on its design, but I went with a 3 since it doesn't come with the gauge.
