I was in Atlanta for a wedding and ran out of my usual stuff. Took a shot and glad I did. The pre-rolls were rolled tight and burned even the whole way down.
Placed my order Sunday afternoon and it was at my door Tuesday. Communication was steady throughout, someone actually replied when I asked about shipping instead of ghosting me like other spots do.
lowkey these edibles snuck up on me. ate two thinking I was tough and ended up on the couch watching cartoons for 4 hours lmao. flavor was decent too, not that chemical taste you get from some brands
I had a lot of doubts going in cause I've been ripped off before online. These folks eased that pretty quick with how they communicated. My order arrived and everything matched what I paid for.
Second time ordering from them. Same quality, same speed, no drama. That consistency is what keeps me coming back honestly.
bro the edibles knocked me OUT last night lol. ate two gummies thinking I was tough, woke up at noon fr
Only my second time buying online period. Everything was easier than I expected honestly. The pack showed up sealed and fresh.
Been a repeat customer for a minute now. They stay consistent, and that’s what keeps me around. Fast delivery and real communication every time.
pack was straight. delivery on point. no complaints
Third order in and they still locked in. I don't leave reviews often but these guys earned it. Communication been solid every single time.
I had a small issue with my first order, one of the disposables wasn't hitting right. Reached out expecting the usual runaround but they replaced it within a couple days no questions asked. That kinda thing goes a long way with me.
I was passing through Vegas for a weekend and needed something reliable. Ordered in the morning and had it before dinner. Whole vibe was professional and I felt looked after.
third order in and im satisfied. same quality every time. thats what matters
Ngl I almost didn't order cause the site was new to me. Ended up trusting my gut and it paid off. Everything showed up sealed and discreet.
Ordered late at night not expecting much. Woke up to a tracking update already. Disposables were legit and hit clean.
real talk I was on the fence about using crypto for the first time, felt sketchy to me. but the dude walking me through it was patient and didn't rush nothing. order landed two days later exactly like he said. lowkey earned my trust with that one
