Proven, simple way to preserve wine
I have only used this product for one bottle of wine so far. Here are my impressions, after reading the directions and utilizing it once, it is a simple process. It is a simple mechanical process. No complicated electronics, no fan to listen to or other devices to break. Does what it is supposed to do, preserve and dispense. When dispensing and preserving, you have to make sure that after use the lever is in the off position(very important) or wine will dribble out of the spout or Wine Gas will continue to pump(to a certain point, I believe) into your wine bottle. After having another device which was relatively noisy and periodically problematic, I am enjoying the simplistic design and peace and quiet. The main lever feels like it could have a better 'solid' feel, but it does work fine. It would be nice to have something to catch any wine drips after pouring a glass, it does seem to drip once or twice after dispensing. This model(the PRO) I believe is the best value utilizing the largest Wine Gas tank since this will be a recurring cost as compared to other products without additional costs. Also, you do not have to change the tank as often when compared to the capsules. It would be nice if the cost of the Wine Gas would come down over time, however, this is a relatively new product. Overall, so far, I would recommend this product. I like the package that Wine Enthusiast has over the 3 models available on the manufacturer's website. It combines the best of all three models, the PRO model(really the difference is the Wine Gas tank vs. capsule) and a variety of wine stoppers, 2 for still and 1 for sparkling wines. From others' experiences, I do believe that science shows that Argon is the best gas to preserve wine, this is from what I have read and not based on experience. Cheers.
