The new Series 40 ball bearing Orbit Blocks™ provide the perfect balance of strength, performance, and reliability. They offer class-leading dynamic and static load ratings, the highest available in this size of performance blocks. Lightweight and strong toughened glass fibre reinforced nylon cheeks replace stainless steel straps used in traditional utility blocks - the perfect balance of performance and reliability.
As well as traditional single swivel blocks, the range also includes single and double sheave lashing or soft attachment options through to multiple sheave blocks including those with quad and quin sheaves. The range is extremely versatile allowing a multitude of possible systems right up to a 12:1 purchase mainsheet system for off-the- beach performance catamarans.
Series 40 Orbit Blocks™ are fitted with our carbon reinforced C-Cleat™ for secure rope holding with low entry and exit efforts, and fairleads for fast action from any angle. Cleat arms are made from stainless steel and are adjustable for setting to your preferred cleating angle.
Ball Bearing versions incorporate our 2-stage bearing system using ball bearings to minimize friction and a secondary full-contact bearing to maintain low friction across the full working load range.
High Load versions are designed specifically for any application where high dynamic or static loads are expected. They feature a high strength grade 2205 stainless steel sheave & hub together with a triple bearing race to maintain low friction at very high loads.

good camera
Style: Dual Dash Cam Without Card
I'm in love with this camera! I've wanted to put one in my car for a long time for my safety, and I absolutely love this one. It's very easy to install, the setup was simple, and the video quality is excellent; everything looks sharp, both during the day and at night. The camera is small, but you can remove the micro SD card and put it in your computer, and everything looks perfect. I feel much calmer and safer driving knowing that everything is being recorded.

Extremely affordable and good quality for price
Style: Dual Dash Cam Without Card
This dashcam might not be the most advanced, but it 100% does the job you need it to. For the price, it's unbeatable. I got into an accident in November 2025 and this dashcam captured the incident clearly, allowing me to be paid out with my claim being 100% ironclad not-at-fault. If you're looking for a good dashcam that doesn't require an app to use or extensive wiring, this is the one you want.

doesn’t come with a bag to store razor after use
This came charged and was easy to use. I love the double sided razor concept, it made it easy to shave upwards and down at once. The speed is amazing getting enough hairs each stroke. It made it easy to get a clean shaven look by simply holding the skin taut. The battery life was well, I used this for half an hour, and it remained speedy and effective. I also did not find that my skin got irritated. It just felt smooth afterwords but irritation wasn’t my biggest concern as I would have applied an aloe gel to soothe the area If i found any irritations. Overall the quality was nice. Although, I will say I was expecting a small bag to be able to set the razor in after shaving since it just came in the packaging.
