Input: Consider Input: By something else. This is the worst piece of machinery I have ever bought. Virtually impossible to cut any size tile on the diagonal. Typical imported junk!!!!!

Output: Negative

Input: Consider Input: Good, sturdy platform for squatting under a barbell. Very firm. Laces are long enough to wrap around ankles, and back of shoe forms a fair notch to retain the laces and keep them from sliding up and off the shoes - would have been better had there been a rear loop. Shoes are better without the insoles because they put a spongy foam wedge under the heels. I replaced them with thin flat insoles from a pair of water shoes. One could cut the foam wedge and use the included insoles. There is no raised heel other than that foam wedge. They run true to size or slightly tight.

Output: Positive

Input: Consider Input: I'm reviewing all three Albums together as they are by the same artist; Regina Carter. Again I purchased these Albums on the basis of a 30 sec listen. They all lived up to my expectations. If anyone is familiar with Stephane Grapelli, Regina Carter's style is very similar. She really swings. I love these albums and play them over and over again.
Output: Positive
