The best thing about crustlab, they're always ready to help you with anything that comes up in your project! They have been very helpful at every step of my career as an engineer working for them so far (2 years).
I can't think any problems or concerns yet either because everything has gone smoothly thusfar :) Highly recommend their work ethic & professionalism!! If there's something i could suggest it would be more frequent communication between team members when things aren't going well like deadlines etc., but other than those few issues we've had no real complaints!
