PINGEUI 2 PCS 16 Inch Lab Stand Set, Laboratory Stand Support, Lab Stand and Clamp Set with 4 Retort Rings, 2 Flask Clamp, 2 Burette Clamp for Lab, Scientific Glassware, Labware

My order was sold by "QY-PINGEUI". There are so many things wrong with this set, I'm just going to list the top ones that come to mind: 1. The burette clamps are badly designed and bind HARD when you get them nearly closed. This makes it impossible to securely grasp anything as narrow as the neck of a flask, let alone a burette. See my first photo, that's as far as they got before binding up. 2. The photos clearly show cork pads on the burette clamps (which is heat resistant), but mine came with the a yellow plastic felt-like material (which melts in heat). To add insult to injury, the felt had mostly fallen off right out of the bag. 3. Everything in the set ships rolled up together in a bag with no padding between items. As a result, everything looks beaten up, the three-finger clamps were bent out of shape, and one even cracked. 4. The base plates are quite light -- both of the ones I got weighed a few grams short of a pound. Don't expect it to resist tipping over if you have an off-center load. 5. On the "stainless steel" rods there are some small low spots where a darker material is visible. The rod is strongly magnetic so I suspect the rod is plated iron, and those spots are places where the plating flaked off. Similarly, 6. None of the knobs are the blue "wing" style pictured, they are all black and round. Needless to say, I'm returning mine.

Llegó muy bien empacado y por el precio la calidad es excelente, buena compra

Good for price. No problems with clamps but base and bar have no weight. Need to make sure and put a weight on it because it wont be steady

Buen producto, relación precio y funcionalidad
