Product Information
Orbit blocks™ are a no-compromise product range developed to meet the demands and expectation of the very dedicated and increasingly professional racing sailor. Side cheeks incorporating head structure and hub are precision machined as a single part from solid alloy, leaving material only where it contributes to the load carrying capacity of the block and eliminating the need for additional fasteners. The Orbit sheave has captive Acetal ball bearings for side thrust loads, eliminating the need for side retainer plates. This reduces weight and allows for a wider bearing surface that can accommodate longer Torlon® needles – achieving a substantially higher strength-to-weight ratio.
Applications
Primary mainsheet, halyard and spinnaker systems on boats to 14m (46ft)
Secondary mainsheet, vang blocks on boats to 15m (50ft)
Standard and running backstay systems on boats to 12m (40ft)
General control line and lead block applications on larger yachts
Materials
Fully machined Alloy cheek plates
Alloy sheaves with captive ball races
Torlon® needle rollers
Carbon black Acetal ball bearings

Good value, but buyers should be aware that the metal base extends only on edges
I think this tray is a good value compared to other vendor's products that are $100+. I plan to keep it because it is a good value for me. HOWEVER, realize that the metal base does not extend across the full base of the cork liner. Metal pieces are only on the edge of long side of the liner. Also, the metal is lightweight.

The Ideal Organizer
The UPERGO Valet Tray is an ideal size for my nightstand. It does not slide around but stays put where I position it. Each section is useful for the items I want to keep close at hand but in an organized fashion, cell phone, wallet glasses, change, etc. I love the cork interior of the tray; it’s stylish and functional.

It's a functional organizational tray
I bought this valet tray for my nephew to be able to organize his go-to items, such as his cell phone, wallet, watch, bracelet, etc. I expected the tray to look more upgraded. The compartments are shallow, but they do the job. It is made of a cardboard-type material ( corkboard would have been nicer), and the black platform is a metal construction, which gives it a more stable and solid structure. Overall, for the price and its functionality, I guess it was worth the purchase.
