I contacted Pelehandmade to purchase a few brass PCB holders which he did not have in stock at the moment. He quickly replied, added stock, and then readily shipped the items after purchase. The items were well packaged and arrived safely. Quality is good, they seem to be turned on a lathe by hand and hand assembled with great care. Pele also included a set of extra oversized o-rings for me. The PCB holders work very well and I'm happy with the purchase.
I found these kind of by accident and glad I did. I ordered a pair (and the seller is wonderful to work with) and got them quickly. I quickly put them to good use. They are well made. The adjustment is smooth and sensitive to the touch. Between the weight and the magnet they are stout and steady as they hold the PCB firm. I am looking forward to bringing them to the next makers meeting. I didn't really rate the documentation as the instrument pretty much explains itself.
