I haven't purchased from Europtical, but that's not enough to keep me from reviewing them.
I have frames I love, I wasn't in the market for more, but the beloved frames of mine arrived in the post wonky and ill-fitting. I walked in, asked them if they wouldn't mind adjusting them for me and with a smile she whisked them to the back and bing bam boom - adjusted!
A month or so later, the frames again began to go a little haywire so I popped in after I grabbed an Americano from the adjacent Caribou Coffee. The gentleman who took my frames warned me that the adjustment came with a certain amount of risk and by the way, the reason they went wonky was due to my removal style. I slapped my own wrist and off he went. A minute later, he came back and made sure they felt better (which they did on the first try) then sent me on my way. Both adjustments free and with a smile.
Sadly, about two hours later on a flight to Chicago, the overhead bin opened during takeoff which sent a bag careening towards my head thus knocking my glasses to the floor and out of shape. I'll be visiting Europtical for yet another adjustment and while they never suggest I do, at some point I should probably buy something...
