This works pretty well. I don’t have a Stanley but it is a cup similar and this topper worked for it. I’m not sure why this wasn’t just an adapter right to the flavor cartridges but it needs the top of a Cirkul cup. It seems a little much to have it all stacked up. But regardless it does work well and does not leak. Overall, I am happy with this adapter.

I love both my cirkul and my Stanley so this was exactly perfect for me. The lid fit my cup perfectly and most importantly, does not leak! I love that I don’t have to switch cups to use my cirkul or buy another cup that I very much do not need

So this adapter is made to still use the lid from the cirkul water bottles and then the cirkul flavors. Its made to fit a stanley style tumbler. It fits perfectly on my generic stanley tumblers. So i have tried cirkuls official tumbler and i HATE the way its made and has this awkward straw piece and collection area of the water. This does not have all that. Honestly making it easier to clean and much more sanitary. Also the official cirkul tumbler has suction issues and is difficult to drink out of unlike this. Dont spend $50+ on cirkuls tumbler and just get this if you're a fan of cirkul and want to use a tumbler instead.

Had no problems. Worked perfectly with my Stanley and Cirkle cartridges. I would be careful and double check which Stanley cup you have though. Lots of different styles and they are not all compatible. Kind of a pain. As for this, excellent product.

Fits my off-brand 40oz just fine so doesn't have to be a staaaaanley. But another review saying extra piece had me confused and realized they meant the cirkul lid. Not sure why you'd by cirkul pods without a cirkul bottle, but there you go. It is semi-related to my negative still that I don't want to have to use my cirkul lid. I would prefer if could put pod into it.

I found this adapter for the Stanley to be very basic and plastic. I was disappointed that it doesn’t state clearly in the directions online that you have to have another piece that goes along with this device in order to use it properly. Soit is of no use if you have just a Stanley without the additional adapter.

This fits my 40 ounce Stanley fine. I did not realize you had to buy the circle lid also. I just thought maybe I could use the pods with the lid which would’ve been nice. So I am not able to use it because I do not have the cirkul lid

I ordered this for my brother's 40z Stanley Quencher. Messed with it for about 10 or so minutes and could not get it to line up and screw on to make a good seal. This was a Christmas gift for him and it doesn't work. Since I got this item for free I can't return it or get a refund I guess you get what you pay for. So now I will have to buy him the official Cirkul 40oz. All-Day StrawSip Tumbler instead. Not Happy.
