I was a regular here for over a year. A few nights ago, I purchased a live resin cart. When I tried it later on, the cart had leaked which turned the silicon yellow, and the cart was clogged. I called ASAP the next morning, and was told I could exchange it. I bring it into the store, and then i’m told they have to test it. The manager tests it and all he says is, “no it works fine, try another battery” he kept cutting me off and had no interest in what I had to say. I take it back home and just give it another try, still nothing. So i call back hoping to speak to someone else, because regardless it still leaked. I end up speaking to the same person again, except they decided to yell at me, gaslight me, and make me feel like i’m wrong for just trying to get the product I purchased. “Sorry you feel like your cart leaked” is what I was told, and was spoken to so condescending. Finally i’m told I can call the company, and when asked if thats what I was doing the MANAGER hung up on me. The company after I called them, took one look and said “yep your cart is faulty” and sent me a credit. Why was that so difficult? Thankfully, the staff I dealt with when redeeming my credit was completely kind and understanding. If I could give certain people at this store 5 stars, I would. However, I will be going to Remedy now, because I don’t need to be screamed at or called a liar if I have an issue with a product.

Once a long time customer but the receptionist ruined the experience for not only me but countless others. Their internal store only rule (not MD regulation) of no recreational service prior to 11am, despite having all their information say open at 10am is troubling to reconcile… As I arrived 15 mins before 11, I rudely told I couldn’t wait in the lobby and watched the receptionist turn down at least 5 customers all while the store was completely empty of medical (or any) customers. It’s a shame as the budtenders are extremely nice and knowledgeable but good luck getting past the the dragon they have as a receptionist. Plenty of other dispensary with much friendly staff and significantly better prices and product offering. It’s a shame their receptionist service is so poor.

The staff are always so helpful and nice, they answer any questions that you may have. They make the whole shopping experience mello and easy. Jaeden is awesome, he helped me out, he made me aware of the Veterans discount and let me know about upcoming sales and specials.
