Mr M P.
AVOID.
AVOID. Like a previous reviewer, I found the quality of shots that came from their 6 and 10 stop screw on filters poor, when compared to a more costly brand. i also have the square filter system when you attach the holder to the correct adapter the holder just keeps spinning round, so use less. I only contacted them to say about the products as I had had the filter some time and it was not useable and the others produced poor shots, so all I wanted was for them to remove all of my information from their system but the hassle I had to go through for that. They say now they have done what I requeted but somehow i dont think they will have done i just dont trust them. as the saying goes "Buy cheap buy trouble" Oh yes forgot to say sliding the variable filter in and out of the holder virtually impossible. Anyone reading this will see they have replied and now say "If I am open to it" to contact them, all this since my review. They had a chance and all I got from them was excuses and one mail a day so it dragged on. first the wanted order numbers, then video proof, then I was told the team that did what I wanted was on holiday!! one mail the wording said "If indeed the products are ours" seemingly totally not believing what I had told them. So Now I wont be taking up their offer, they did nothing when they had the chance, so as stated I will noyt ever buy from them again.
