Product Information
Lightweight
Kilogram for kilogram of working load, BB and RT Orbit Blocks are the world's lightest. The unique orbital design allows the bearing to only be in the active areas of the floating sheave. This minimizes the mass of the inactive return race and hub.
Weight and bulk are further reduced in the different block configurations. The ball bearing single and becket block has a through-sheave becket arrangement. The result? The lowest weight possible.
Multi-sheave blocks have only single intermediate cheeks and an ultra-light and efficient head arrangement. This gives a 30% weight saving advantage over the nearest competitor. Other brands just link together their single blocks. This results in unnecessary double cheeks between each sheave, held together by a heavy steel channel across the top of the block.
Highest working load in its class
The orbital ball-bearing arrangement gives the largest possible bearing race diameter. This maximizes load performance. The proven Ronstan 2-stage bearing system features high compression grade acetal ball bearings and a secondary full-contact bearing. This gives minimum friction across the full working load range.
The floating sheave and bearing system is supported by a fiber-reinforced load frame. The design was computer modeled to be stress optimized.

Excellent Cigar Tube!
Color: RYLCC-BLK
This impressive cigar carrier is a complete and safe way to carry one cigar. This holder is light aluminum; you can throw it in a range bag, backpack, or any other carrier without worry. This carrier has a punch for your cigar and a built-in cigar stand. I love my cigar carrier; I have just enough capacity to enjoy my cigar.

Picture is misleading
Color: RYLCC-BLK
Great product! Good quality! The picture of the product is a little misleading as it looks like there are 2 tubes instead of one.

Perfect sized wrist-rest!
Size: Compact, Size: Compact
Great wrist-rest! Very squishy and feels comfortable & cool even after hours at the computer. The rubber gripper bottom is effective & it never shifts around for me. Also, love that it fits the length of my 75% keyboard & my boyfriends 60% Wooting 60HE keyboard perfectly

Very Pleased!
Size: Full Size
Review for: Cooling Gel Wrist Rest Pad -Full Size 18"- Memory Foam Palm Rest with Non-Slip Footpad - Ergonomic Design Wrist Support - Desk Keyboard Accessory Gaming Gear (Large-Full Size). I've had this for a week and I'm impressed! There is no skimping on quality, which is rare nowadays. It is made extremely well, solid yet soft. I love the feel of the outer cover. It's comfortable and stays in place. And let me add... I'm putting it to the test. I have a rolling over-bed/couch desk. It has a raised 1/4" lip around the top. I put this wrist-rest on top of that lip. So far there's not any wear across the bottom of this wrist-rest. And that's with me using it for my wrists... and my elbows. It far surpasses the last rest I bought. From my experience, many sellers slap the phrase "memory foam" on their products when they are not. That's NOT the case here. This rest immediately bounces back to its original shape. It's true memory foam! It's so comfortable that I forget it's there yet I enjoy the comfort immensely. Also, it has no smell. ***From my experience so far... I highly recommend this product!
