It is arrived quickly as usual. I read the description and bought that R134 adapter a head of time. Once I have everything ready to go, I got R134 small can from home depot for $10 and started the process. It was very clear that our Kenmore fridge didn't have enough refrigerant. While I was watching the pressure I slowly released the gas and bingo. Now the fridge is cooling very nicely and not anymore high temperature warning. Great DIY tool and I suggest everyone.

Great product, & the lowest price on the net.
