Mr Nice Guy Cannabis Marijuana and Weed dispensary - Costa Mesa Harbor Weed Accessories

Online order, product was wrong.. manager offered no solution.. I told them I’d pay for an upgraded product they offered none.. solution was go to another place and buy a battery for your product.. I wasted $10 on a tip.. no more business from me.. bad staff including manager…

Harli is Amazing!!!

Harli is awesome and really helped tailor products to my needs. She is so knowledgeable and also so sweet. Harli was a blessing to work with. People really do make the difference as most shops have a lot of the same products. Thanks Harli! We will be back and hopefully get to work with you again.

Amazing

I love this place! It was my first time going to a dispensary in OC since we are from SF, we are vacationing here in Newpot Beach and I was worried it would be expensive since it's in the city, but I was pleasantly surprised by the prices and quality of service. The staff members were all super friendly and had some great recommendations.I got everything for 30%!!!
