Happy with opener so far, had a little trouble with the auto close stopping 6 inches before latch several days after working fine. We called customer service, had to leave message and they only do lifetime support via email because they are in China, so we had to figure it out ourselves. They finally gave us a number in China for emergencies... which i am sure will be expensive and may not speak English.
Your support staff Zack was extremely helpful in helping me get the parts that I needed, and any request for additional information I received a timely response.
I would recommend Topens to friends and family.
