Lol I just went to the link you provided and clicked on the sf series page. Here is what it says.....8 models.After reading many of your comments, I guess no one has found our new product yet! 😎 We will send you the link, please count the number of models in the SF series: www.spider-farmer.com. We have updated the information on our website. We hope you can grasp this opportunity, after all, the final prize is very big, it is SF4000!!!!!!!!!!!
I'm really wondering what the F is up??
