I've been a member for about a month now and here are my thoughts.
1. Customer service is amazing and I think this is most important. You don't have to be fearful that if you try it out and have a bad experience you'll be out your money... They are so easy to work with to make things right. That alone makes them worth a try.
2. The reviews about the techs being inexperienced are all very true. I think the manager should really have a sit down with them... Because a lot of the issues are easy fix! One eye at a time is an issue, it does definitely cause them to be uneven or different in appearance. The manager may need to block time for them to practice on each other and critique each others work. It would be worth it in the end. With that said, there are some that do a good job, the key is finding someone you like :)
3. Super clean and comfortable, this is very important for safety purposes.
4. Glue... I find it to be stronger than others I've tried. I have issues with lash fall out no matter where I go, but it's been a little better here. And the prices make getting frequent fills (for a chronic lash looser who sleeps flat on her face) to be less painful monetarily.
Conclusion: worth the money, safe investment, excellent choice IF you find the right tech. I think in a year when they all have more experience it'll be an easy 5 stars.
