I've bought a few things from K&F Concepts over the past few months. ND filters, a Camera Backpack, and a tripod. The magnetic ND filters are wonderful (see an example of a long exposure with K&F Concept 1000ND filter attached), these make me very happy.

The bag I bought was very good for the cost (around £70, but have since changed this again as my kit size and level have changed a lot, but that's no poor reflection on K&F Concepts, I simply needed a larger volume.

The tripod was an unfortunate experience, I had some issues with it and returned it for a full refund., which K&F Concepts honoured without any fuss. Great.... I then received an email from K&F Concept's Customer Service Manager (Rina Kuromiya) reaching out with concern about my review of the tripod. I was offered a compensatory gift which I had a choice of either picking anything from their product range to the value of the tripod I purchased, or I could take a gift voucher of a set value. I chose to take the products from their range and have even more magnetic filters from them and I couldn't be happier. Delivered the following day!

K&F Concepts' aftersales service and customer care are amazing. A lot of other companies could learn a lot from these. Yes, I would highly recommend them and will be purchasing more equipment from them in the future. - if Rina Kuromiya is reading this, I thank you sincerely, and would be more than happy to be a product tester for K&F Concepts ;)
