Ordered this yesterday and it arrived the very next day — really impressed with how fast the delivery was. I wasn’t home when the courier came, but they were great about it and left a reference number so I could easily arrange a new delivery time. Smooth process overall, well packaged, and great communication throughout. Will definitely order from OP Labs again.
