I had some fun using this product. It was interesting experience and I think it's a good idea to check how much you sweat and what you lose with the sweat. The product is very simple to apply, just followed the instructions. However, it's not complete without the app, and this one is terrible. They tried to make it so simple to use that actually made it not user friendly. It's confusing and there is no option to go back or check previous workouts. Also, it's sync with health app and bring all workouts you made on the day, and there is no simple way to delete them. You need to open one by one and delete them. Very good idea, very frustrating execution. If the app was better, I would probably keeping using the patch once a while just to check my sweat.

I guess I didn’t get it on good enough because it fell off and disappeared somewhere in the grass during the soccer game. I definitely plan to try it again, but make sure that it is stuck on there really good because losing it was a big bummer!

The idea behind this product is awesome. The directions say to place the patch on your forearm just under your elbow. What I realized though is that I guess that’s not a place I really sweat? I definitely had a sweaty workout, but the sweat didn’t collect in the patch the way it was supposed to because that particular spot didn’t have much sweat. I’m not sure if you can place the patch somewhere else instead. If so, that would probably be a lot more effective for me.

Helps tell me more info on my personal sweat patterns. It was good but also i wouldn’t buy this outside of this box bc its not necessary. You can get helpful info from a smart watch.

I went for a 30 min run in 90 degrees and sunshine and could not get the patch to have enough sweat to read. So, I couldn’t get a hang of it to actually get the reading.

I think the concept of the patch is pretty neat. I enjoyed seeing my sweat progress in the patch itself. However, I don’t find this necessary to the average gym goer. I think this patch is ideal for those training for a big event or your super serious gym rats. Overall it was neat, but not essential in my book.

I spent a pretty long time doing a high intensity workout but I guess I don’t sweat much on the inside of my arms because it never filled up more than like 1/4 of the patch. Other than that it gives ok suggestions on stuff like rehydrating

It was interesting. Super easy to use but I’d say more instructions would be nice like weigh yourself before and after (tell me that before I workout and use it). I’m not sure how accurate it is because I sweat a lot and I didn’t feel like it filled up enough
