I initially purchased my first Slim Two as part of Kickstarter campaign; however, it stopped working in less than two years. I really like the product (when it works), so I replaced it. Big Mistake! The second Slim Two stopped working after 1 year &  5 days. Well that is 5 days after warrantee ended. The repair cost is almost the entire cost of the product, so I will be looking for a higher quality manufacture this round!
