Product Description: Once a bottle of red wine is opened the wine is exposed to the air and starts to oxidize. How to slow down this oxidation process and prolong the wine shelf life is a concern for all wine lovers. Due to this we have developed this Intelligent Vacuum Wine Preserver. This product can automatically evacuate the air inside the bottle and readily detect changes in air pressure inside the bottle by using supplementary pumps to ensure the pressure inside the bottle to maintain a steady vacuum state to keep the original taste for the unfinished wine and to extend the life and freshness of the wine. This product can also record and display the storage time for the stored wine and can display the wine storage temperature to ensure the product is as fresh as when it was first opened. A built-in rechargeable battery and an LCD display ensure the utmost convenience for the wine lovers. The product is designed with fashion intelligence visualization and portability. It comes with two stoppers for multiple bottle usage at the same time. It is a must for all wine lovers. Product Features 1.Electronic monitoring automatically vacuum built-in vacuum pump 2.Automatically supplementary pumping to always maintain a stable vacuum inside the bottle 3.With dual functions of split or combination you can use it for many bottles of wine and easy cleaning 4.Automatic Tilt Shut-off Feature to ensure the safe use 5.Wine storage time records to show the best time to drink 6.Always shows the updated temperature 7.Built-in battery: portable to use long standby time 8.LCD display: convenient and practical Product description and maintenance: 1.The soft rubber sealer can seal the wine properly and it can intuitively show the pressure changes in the bottle. This rubber stopper is made of food-grade silicone (it’s widely used in such as bread trays pacifiers and other materials and it can bear the temperature -40ºC to 230ºC). 2.The main part is used for vacuum and testing the air pressure inside the bottle. Each pumping time is 90 seconds. - After the exhaust is completed you can pull off the main body from the wine bottle leaving the wine stopper. This method can be used for storing many wine bottles. - To seal the wine bottle you can also choose not to pull off the body part which means it will always help to detect the bottle pressure condition 3. The benefit of the main body in conjunction with wine stoppers is that you can use the body to pump different wine bottles. This method allows for a more convenient and effective use. In addition this product can be cleaned. It’s more sanitary and will not affect the wines taste for future use. 4. The timer function allows you to know the best time to drink your stored wines according to your own taste. You can also manually setup time records. Time is recorded by days. After turning on the main body it records time from 01 (the first day) . (Additionally you can add previously storage days in the timer mode manually.) NOTE: When shake the preserverit's normal to hear the sound which is made by the buit-in anti-leaning switch. <img alt="" data-cke-saved-src="http://m5.img.dxcdn.com/CDDriver/img/sku_364999_103.jpg" src="http://m5.img.dxcdn.com/CDDriver/img/sku_364999_103.jpg" style="width:" 600px;"="">
