Customer service is very good. Always fast and helpful responses to queries whether by phone or email. Normally stock levels are good which means orders arrive reasonably speedily. The range of options for fly tying materials is good. I like the briefing emails on fishing techniques and rigs which I think is a differentiator from Essential Fly's competitors. One area where there could be an improvement is the search function on the website. You often get irrelevant choices and you can't narrow the options down. This can be very frustrating when you know what you want but have to trawl through loads of stuff yo get to the item(s) you want. Overall very satisfied which is why I'm a long time repeat customer.
