Here are the items that I bought from Drop in the past:
- GKs Matcha Dye-sub Keycaps
- Sennheiser HD6XX Open-Back Headphones

I had a smooth experiences in both orders, with the latest turnaround being a month.

The products are decent-quality, and I daily drive the headphones. They were excellently packed, and decently priced compared to similar products.

I don't mind the pre-order model, I'd just prefer if they stick to that instead of limited-quantity group buys going forward.
