Can make a little noise though if you are not carefull
That' s the problem I' m having with mine. They say you can quiet them down by using a file on the " teeth." Not sure what the proper term is...but it' s the two parts that look like teeth that grip the tree. You can file the finish off with the file exposing the aluminum...suppose to eliminate the " creak." I haven' t tried it yet but plan to.
Other than that...Summit' s are perfect.
