Harley Benton Bottleneck/Slides Set Metal

The smaller slide is slightly big and so it's awkward to use the finger it is on to play normally, but moving between strings is smooth which is a problem i have with most knuckle slides.
The bigger slide is ok. It's a little thin, both physically and tonally, but it's a great fit for my middle finger.
Overall I don't use these but it's always subjective when it comes to slides.

Quality is good (ok, it is just a steel tube). But it is quite heavy. Need to pay attention not to drop it while playing and it gets tiring after a while.
