I am new to loupes and have been researching for a while now while trying out others' to see what to look for. Ordering from a company that isn't local always feels like a bit of a gamble...but the TLC makes it so easy! The entire team was incredibly friendly and professional. Simply the best customer service to answer my infinite amount of questions. They stick by their products and guarantees, and offer quick and fair solutions to any issues that arise. I could not be happier with this group. I ordered the flip up loupes with the halo light for use during electrolysis treatments. The quality is so much better than the other brand of inexpensive loupes my coworker let me try, and the price at TLC is excellent. I think these would be perfect for those doing training as the PD is adjustable while the 5x image is crystal clear. These are a bit heavy on the nose, as to be expected, so I may try the Ergo unit too if I don't get used to it (will update the review if so). I will recommend them to all my coworkers as the BEST option for high quality products and high caliber service. For reference, I am in BC, Canada and they operate out of the UK. Still had amazing turnaround time and fast responses to my inquiries. Feels so good to be treated like a human, by a human, instead of like a number by a robot.
