I was told that Alvin is good. I've tried Alvin once, the design is OK...He's nice, he offered me free litter which can cost me $10 extra. However, the shape was not good, I don't like it. I've never had lifting or crack or broken nails before, but I must take them off and come back for a full set...cause, they were all lifted and fell off..what a wasted...I gave 2 stars for designs and -1 star for quality of Nails....
