Someone recently mentioned that Vello makes an extension tube set which appears to be quite similar to the Kenko set (both are listed as Auto Sets). What benefits does the Kenko set offer over Vello? Both have good reviews although I'm sure the Kenko set is well known and trusted. Other than Kenko's reputation, are they any physical differences between the two such as one is easier to operate? Surprisingly the cons for the Kenko set on B&H list it as not being durable. Any suggestions? Thank you!
