For the price i?ve been very satisfied with this, so much i?m getting a few more! This was my first PB and it does the job without making a fuss.
Bought one a year back to keep stuff organized in a permanent but flexible way in our soon to be permanent production-rig, anybody can just plug their sources in easily and their stuff goes where i want it. Worth every penny.
No loose springs or slippy contacts so far, but i do exercise them once every few months just in case.
My reason for giving 3 stars on handling is this:
The fitting of the element-boards OTB was pretty hamfisted but it?s only two screws and a little patience to make them all sit as they should, i recommend taking the time to check if the front chassis is bulging when you get yours. No soldering or intrusive stuff, just a little fidgeting.
Quality-wise it?s a pretty safe expense since if a few elements start to fail you can get replacement units. I have not had to replace anything yet though.
