Conclusion:Despite the questionable choice of silicone, the mouse is fantastic overall and performs as a top-tier option in my opinion. I hope this info helps. Overall, Im very satisfied with my purchase. The whole thing is flimsy and poorly manufactured. I read a lot of bad reviews but after all I am so glad I bought this product. Two to a box. They are also well made. I?ve been wanting a pair of these shoes for 10-15 years. Her foot surgeon recommended them in 2016 when she had major surgery on her left foot. This was the first and only pair of Naturalizers Ive purchased on Amazon and not only were they not comfortable, but they didnt last.
