Hello Roger,
I am very glad to sell Tunze products in Taiwan and feel very excited about your new products. I know there are some copying products from China. At first I was worried about them due to their low price and since we are very close to China; however, so far I found they don't threaten yours. Because most customers know what's the difference there, your products are seen as the state-of-the-art ones. I will spend more time on promoting and selling your products and do my best to provide customer service for your products here in Taiwan.
Cheers.
