问大家
: What's the difference between C1-H and C1-G? Does G stand for glass, and which component is it? Are the other functions the same? C1-H 和C1-G有啥区别？G代表是玻璃的，是哪个部件？其他功能都一样吗？
回复 @相约2017 : Hello, due to the recent sales of C1H far exceeding expectations, our inventory is depleting very quickly. We've noticed that the front-end currently shows only 1 item left in stock, which may cause delays in page updates. We recommend refreshing the page immediately and trying multiple times to add the item to your cart and complete the purchase to see if you can successfully secure it. If it still doesn't work, it might indeed be sold out. But don't worry, we will update with other discounted products from the same series later. Please wait patiently. 您好，由于近期C1H的销量远超预期，库存消耗非常快。我们查看到目前前台显示仅剩1件库存，这可能导致页面更新延迟。建议您立刻刷新页面并多次尝试加购下单，看能否成功锁定。如果还是不行，那可能确实已售罄。不过别担心，我们晚些时候会更新同系列的其他优惠产品，请您耐心等待一下
: Hello, the C1-G comes with an additional glass cup as a gift. The main functions of both products remain unchanged. 您好，C1-G是外加送一个玻璃杯，两款产品主要功能没有变化的～

The contact information is: Email: service@waterdropfilter.com; Phone: 1-888-352-3558 (U.S.). 您好，请问产品型号是A2吗，在水滴键闪烁的时候开始点击，就出水了，您可以再重新尝试一下，如果还是出现问题，您可以联系我们的客服进行反馈，相信会得到解决办法，联系方式是：邮箱：service@waterdropfilter.com；电话：1-888-352-3558(U.S.)

回复 @姬尼美 : Hello! Thank you for your feedback! The countertop water replacement process involves three steps: "remove the water tank → empty it → refill with water".

It eliminates manual water changes, provides instant use with just a turn of the tap, and offers a higher water flow rate, making it especially suitable for busy large families~ 您好！感谢反馈！台上式换水是“取出水箱 → 清倒 → 加水”三步，如果您想省掉换水步骤的话可以考虑一下我们厨下款哦，免去手动换水，即开即用，而且出水量更大，特别适合热闹的大家庭哦~

: Does this machine contain scale inhibitor? 这台里面含不含阻垢剂？
: Hello, the scale inhibitor in front of our RO membrane is designed to protect the RO membrane by preventing the water concentration before the RO membrane from becoming too high during use, which could cause scaling and clogging on the RO membrane. The RO filtration precision is fine enough to intercept the phosphate molecules of the scale inhibitor, preventing them from reaching the purified water side. The scale inhibitor components will be discharged with the wastewater, so you can use it with confidence. 您好，我们RO前面的阻垢剂是为了保护RO膜，防止使用过程中RO膜前的水浓度过高导致在RO膜上结垢堵塞，RO过滤精度足够细，可以拦截阻垢剂的磷酸根分子，不会来到纯水侧，阻垢剂成分会随着废水排走~可以放心使用
