May 23, 2026Quality products, reasonable prices, nice and helpful staff, constant discounts almost every other weekend on top of the reward system , interesting reads in your email and finally some good merch. Delivery is fast and I have never had misshaps or packages missing so far, which is more than I can say compared to other companies of similair nature. Descreet and safe packaging and overall a general sense of friendliness, passion and attention to quality. In other words - good sh&t. Highly reccomend. Site is easy to use and navigate, various forms of payment accepted and if you have a question it is usually answered within a minute or two. If I could I'd work there myself. Hope that helps!
