Communication was probably the thing that stood out most to me. I had an issue with my address and they fixed it same day without any attitude. Stash arrived two days later exactly like they said it would.
bro whoever picking these strains got taste fr. the purple punch had me sleep by 10pm lmao
Really appreciated feeling like an actual customer instead of just a number. They followed up after delivery too. Product was fresh and hit as expected.
Flew in for a conference and needed something to unwind after long days of meetings. Found them through a friend of a friend and figured I'd try. The disposable I picked up was smooth, hit clean, no headaches the next morning. Prices were a little higher than what I'm used to back home but the quality made sense of it.
Carts been hitting lately, no clogs, no burnt taste, just clean pulls every time.
Fast, easy, done. Prices reasonable and the stash was fresh.
Was staying with my cousin in Miami and he put me on. Glad he did cause the flower was fresh and the whole process was smooth. Might order again before I fly out.
Traveling through Houston for a few days and needed something reliable. These guys handled it with no stress. Appreciated the professionalism honestly.
lowkey didnt think it would land that fast. carts hit clean no burnt hits or nothing. good looks bro
Third time ordering and they haven't missed yet. The Wedding Cake this round was sticky, smelled loud through the bag, and had me knocked out by like 10pm. Prices stay reasonable too which is why I keep coming back.
I appreciated how patient they were with my questions. Being a first time buyer I had a lot of them. Everything went how they described and the flower was fresh.
Not bad at all. The pre-rolls burned clean and the price was right. I'll probably grab a bigger order next time.
my guy came thru with the gas no cap. shipping was faster than i expected. good looks
Pricing was fair, buds were fresh, and delivery didn't take forever. Not much else to say. I'll be ordering again soon.
Was passing through for a conference and didn't know anybody in the city. Found the site, took a chance, and honestly the whole thing felt way less sketchy than I expected. Buds were fresh, dude who dropped it off was polite, and the price wasn't tourist tax either. Appreciate y'all.
Ain't gonna hype it up too much but the gas was legit. Delivery took like a day and a half. Fair prices.
