This is not an expensive item relative to other jobs, but does the job well. Not as warm as full-winter gloves, but they are pitched as moderately warm and do just that. Easy to use touch-screen phone with the gloves on too.
As others have noted, the sizing is VERY small - I technically measured an M, but ordered an L and the L's fit a little tight. It's fine for use on the bike (or, say, running) because you don't need to move your fingers all that much. But if you are using the gloves for something else I would order two sizes up or find another alternative product.
