Works great when used as directed
These are great for freezing away warts, skin tags and other blemishes.  These are not designed to be attached to the can but to be pressed against the skin with the target inside the 2,3,4,5,6 mm hole.  The speculum is then filled with the cryoliquid of your choice and contains the liquid while it works its freezing magic against the target.  Thus ONLY the target area is frozen and the surrounding tissue untouched.<br /><br />Other reviewers suggest using tape to hold the speculum onto the skin.  I have not tried this but in retrospect it would have made the job easier.
