Love the products and the crew. My only question is why does it always smells like BO every single time I walk in?

First time at Ethos, a friend recommended! I always like to experience different types, but the one I wanted was out when I tried to order online. So I ended up still doing a walk-in and explaining to Sophia my situation. Sophia was wonderful, I’ve asked her if she has something similar, but she ended up finding the one I wanted originally! LOOK HOW COOL IT IS! Thanks Sophia!!

New website and app platform at garbage. App is basically just a web client, you can't do anything it doesn't actually show the menu items and you can't order from it it just takes you to a web page. They changed platforms and the ordering process online is useless and terrible. Text message verification won't actually send texts so you can't order online. Not like it used to be where you'd put in your info and just order now it forces you to log in but their log in doesn't even work so basically you can't even order online. Such an Incredibly frustrating and useless website and app.

The customer service at Ethos was 5 stars from the moment I walked in. Refreshingly, the cashier and manager were both eager and proactive in resolving some confusion during my checkout process. Everything was taken care of swiftly and I felt like a VIP while I was there. I'll be back and it's nice knowing my brother has been coming here for years now.

The team here at Ethos in Watertown is really outstanding! Always informative if you have questions and super knowledgeable about the product. If you just need to get in & out quickly, there is rarely a long wait, even if you’re a walk in.

Absolutely horrible service every time I've gone in- forgetful, careless, slow, and occasionally straight-up rude staff. They haven't been accepting credit cards for months now and haven't bothered to fix the issue in their system. Good prices though. 😞

Staff is great, very helpful. Online ordering is very easy, in and out of the store in 10 minutes.

They should be honest with their closing time. If you arrive 9:50pm. Even with a preorder, they will turn you around. Happens way too often.
