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 or Torlon® 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.Halyard blocks are used in applications with a fixed line entry-angle to keep lines close to the deck as they lead aft to organisers and winches. Halyard block has a removable pin for attachment to deck padeyes or mast collar

Primary mainsheet, halyard and spinnaker systems on boats to 15m (50ft)
Secondary mainsheet, vang blocks on boats to 18m (60ft)

Small fan, serious power
Color: Black
I bought the Honeywell Turboforce Fan for my bedroom, and I’m honestly impressed with how powerful this little thing is. Don’t let the compact size fool you — it moves a lot of air. On the lowest setting it’s perfect for a gentle breeze while sleeping, and the higher settings can easily cool down a medium-sized room or help circulate AC much more efficiently.
The 90-degree pivoting head is a great feature. I can angle it upward for better air circulation or point it directly at me when it’s extra hot. It’s lightweight, easy to move around, and doesn’t take up much space on a desk or nightstand. It can also be wall-mounted, which is a nice bonus.
Noise level is reasonable. On low, it’s actually a pleasant white noise. Medium and high are louder, but not in an annoying way — just the sound of strong airflow.
Build quality feels solid for the price, and it’s been running daily without any issues. For the cost, this fan seriously overperforms.
If you need a compact, affordable, and powerful fan, this is a no-brainer. I’d absolutely buy it again.

Nice powerful fan, good price! larger than an average desktop fan, keeps the air moving, and is fairly quiet.

Good value for a powerful fan.
Color: Black
Powerful fan. It’s just a 100 square foot room but you can feel the fan clear across the room. The unit feels durable but it is also extremely lightweight. Easy to move room to room. The fan can face straight ahead or angle to face upwards. It is easy to change the angle of the fan, simply tilt the body and it clicks into place. It does not face downward. When faced upwards it does well to circulate air around the room. It is somewhat loud on higher settings but that is to be expected. At $14.99 this was priced a bit lower than similar units. It’s a good value so far as it is performing well.

Reliable Cooling Power for My Workspace
Color: White, Color: White
This Honeywell TurboForce fan has been a perfect addition to my home office on Staten Island, providing a surprising amount of airflow for such a compact unit. The three speed settings allow me to adjust the intensity based on how warm the room gets, and I’ve found the 90-degree pivoting head incredibly useful for circulating air without having it blow directly on my desk papers. It runs remarkably quietly even on the highest setting, which is essential during long focus sessions or video calls. The white finish looks clean and professional on my tabletop, and the overall build quality feels sturdy enough to handle daily use throughout the summer months.

Small but powerful
Color: Black
This is a small but powerful, 3-speed fan with a 90 degree pivoting head. It's also good looking, lightweight, sturdy, and quiet. The controls are easy to reach and manipulate. The lowest speed was actually too powerful for the location I had in mind for it but I highly recommend it for anyone wanting to cool a room. You can easily cool a small room on just the lowest setting. I'm sad I have to return it but I need something a little less powerful for my desired location.
