Jiayouy 2-Piece IC Pick up Vacuum Sucking Pen Set for precision component placement with Interchangeable Tips and Cups

The black bulb one works fine, the bladder inside the metal tube had a hole in it straight out of the box so it didn't work. Inside of the metal tube was a ton of metal shavings from the machining operation. Some of the tips don't fit on either device due to casting defects. Just overall typical China garbage.... pass on this one.

This product lacked suction power. The quality was lower than the price. While it was easy to press the button or squeeze the tube, it didn't work. I strongly recommend avoiding the purchase of this product.

Looks nice, great idea, but vacuum pressure subsided too fast to actually be usable for anything

I'm glad I ordered the dual version. The short bulb style part worked fine but the pen style unit leaked enough to be unusable. I had the hopes for the pen as it's a copy of a commercial unit I used in a previous life for placing IC's. Fortunately the pen tips fit the bulb unit reasonably well. I'm using this for reassembling small optical components and the bulb worked fine for that.

The big one is basically useless. It has no power and feels super cheap. The smaller one has much better suction power and feels more premium.
