Fave!

I love tanning and this mit is perfect. Very smooth on the body and evens the tan out nicely, doesn’t show up the tan either because the black so even better. However does top cover rips easily so be gentle.

No Streaks

I bought the St. Moriz self tanner after I saw a video review on Facebook by a woman from the States. (I love the tanner, which I will do a review with pictures when I use it again tomorrow.)
The mitt is such a great tool and ensures there are no streaks whatsoever, plus it's super cute with the lip design. It's soft on the outside and inside there is a layer of foam to absorb and hold the tanner. It also protects the palms of my hands from getting the tanner on them and possibly staining. The mitt absorbs the tanner really well, I didn't feel like there was much loss of the product while using the mitt. For the best results I use it in a circular motion and apply it over, paying special attention to blend well around ankles, bend my knees and elbows for the perfect tan.
If you want a smooth, streak free tan - this is the applicator I would recommend. I've just used it with the mousse, so I can't comment on the effectiveness when used with lotion, but I feel the results would be similar.
