Variable ND/ CPL filter
Easy shopping process and delivered within the time frame specified. Filter appears well made and works well on my brief test photos so far. The proof of exactly how good it is will be determined when it gets more intense use. Why a 3 star rating? Well, it was supposed to come with free Bluetooth earbuds but didn't. Customer support contacted me to say I didn't select the free Bluetooth buds option at checkout, although the selection process wasn't clear. However, K&F have sent the earbuds in the post.

Dear Charles, Thank you for your fair and constructive review. Your satisfaction with the filter is important to us, but we are truly sorry for letting you down by not including the promised earbuds. This undermines the trust we work hard to build, and we apologize. We are taking this very seriously. We found that your order came from our distributor Kentfaith. We have contacted them to resolve the issue for you. Please check your email. We hope to have the opportunity to regain your confidence through our actions. K&F CONCEPT Team
