This is the Version 2 from the first look and feel they are going to be great (I hope).
I will try them out later today and write a review.
These automatic clamps are so so good, when you release the string clamp it drops down and releases the base clamp. So you are doing half the work it's quicker and such a neat soloution.
Any 12mm string clamp will fit the base clamp so no need to buy new string clamps!
I have been using these automatic clamps for 10 days now and I really do like them , They make the clamping job so much easier, They are a bit arkward to adust but once adjusted they are very solid on the base with no movement.
I would recommend these Automatic Base Clamps (and no I'm not getting paid to say that nor have I been given the base clamps, I paid for them myself!)
This now goes on my best buy list !
