Innovative Race Functions with Bold New Styling
Ronstan’s ClearStart™ race timer and watches combine contemporary styling with true sailing functionality. They feature large buttons, easy to read displays and advanced intuitive programming designed specifically with the racing sailor in mind. Developed with input from some of the world’s top sailors, ClearStart™ watches and timers are sure to set the standard for years to come. If you’re looking for a simple competitive edge, the difference is ClearStart™.
Large Quick View Displays
The entire ClearStart™ range features oversized digit displays for easy viewing. The Race Timer presents huge 16mm (5/8”) numbers that can be easily viewed by the crew when mounted to the boom or mast base. The 50mm Sailing Watch displays only slightly smaller 13mm (1/2”) digits, which can be quickly viewed at a glance without taking your hand off the helm, and the compact 40mm Sailing Watch still has impressive 10mm (3/8") digits.
Race Sequence Resynchronisation
All racing sailors know how hard it can be to get the watch going at the exact second the start sequence is commenced. With the handy SYNC function, you can quickly resynchronise the ClearStart™to the official race time. A simple press of a button allows you to drop down to the next minute, allowing you to get your starting sequence back in perfect SYNC at the next opportunity.
Pre-programmed Race Sequence Sounds
The intuitive ClearStart™ sound signals let you know exactly where you are in the start sequence without looking at the display. Pre-programmed with World Sailing 5-4-1-0 and Match Racing start sequences, it can also be programmed for other countdown sequences by the user. Sound signals can be turned off if desired.
End of Sequence - Countdown or Count Up
Depending on the user’s preference, the watch can be set up to auto repeat the countdown at the end of the sequence for general recall restarts, or to start counting up to track elapsed time.
Multi-line Display with Real Time
No need to switch between countdown and time modes because the actual time is displayed below the countdown time on the new multi-line ClearStart™ display.
Daily Life Functionality
From waking up for work to working out, a ClearStart™ watch is also great for everyday activities. Standard modes include 12 or 24 hour time format, date in day/month or month/day format, daily alarm and chronograph (stop watch).
Luminescent Backlight
Bright, full-face electroluminescent backlighting is easy to read at night and can be turned on temporarily for a quick view.
Water and Shock Resistant
Designed to survive the rigors of competitive sailing, ClearStart™ watches and timers are water resistant rated at 5ATM and highly shock resistant.

Perfect size and weight with compact size
Style: Rack with 3 Pairs (3, 5, and 8 Pound)
I purchased the Amazon Basics Neoprene Dumbbell Hand Weights specifically for Pilates, and they’ve been a great addition to my routine. The size and weight are perfect for controlled movements, helping with muscle toning without feeling too bulky or awkward.
The neoprene coating gives them a comfortable, non-slip grip, which is especially important during longer sessions or when your hands get a little sweaty. They feel secure and easy to hold through a full workout.
I also like the shape—they don’t roll around on the floor, which makes transitions between exercises smoother and less frustrating. They’re compact enough to store easily but still feel durable and well-made.
Overall, these are a simple, affordable, and effective option for Pilates or light strength training. I’d definitely recommend them for anyone looking to add a little resistance to their workouts without overcomplicating things.

Good purchase
Style: 3 Pound, Pair
These are just the right weight for me to start gaining muscle back in my arms, after a large weight loss. They are of good quality, they are covered in a nice rubber like coating that is soft to the touch. They are small enough that i can take them with me when I travel. My dog has got hold of them a couple times and played with them, and they held up just fine without any damage.

Solid, grippy, and they don’t roll away!
Style: 10 Pound, Pair
I bought these because I’m finally trying to build a consistent home workout routine and didn't want to drop a fortune on name-brand weights. I’ve been using this 10lb pair for about a month now for everything from overhead presses to lunges, and honestly, they’re exactly what I was looking for.
The Pros:
• That Neoprene Grip: The coating is fantastic. Even when my hands get pretty sweaty halfway through a workout, I don’t feel like I’m going to drop them. It’s a much "softer" feel than cold metal or hard plastic.
• The Hex Shape: This is a small detail that makes a huge difference. Since the ends are hexagonal, they don't roll across the floor when I set them down between sets. They also stay put if I’m using them for "renegade rows" or floor work.
• Compact Size: They aren’t bulky. I can easily shove them under my bed or in the corner of the closet when I’m done.
• No Weird Odor: I was worried they might smell like a tire factory (which happens with some rubber-coated weights), but these had almost no scent right out of the box.
The Cons:
• Handle Diameter: The handles are a little on the thicker side. I have medium-sized hands and it’s fine, but if you have very small hands, they might feel a bit chunky to wrap your fingers all the way around.
• Color Scuffs: The navy blue looks great, but if you clank them together or drop them on concrete, the coating can scuff or show dust pretty easily.
The Verdict:
If you just need a reliable set of weights for HIIT, Pilates, or general strength training, these are a no-brainer. You're basically getting gym-quality equipment for a fraction of the price. I’ll probably be back for the 15lb set in a few months!

Simple, Comfortable, and Exactly What You Expect
Style: Rack with 3 Pairs (5, 10, and 15 Pound)
These are pretty much exactly what you want from a set of dumbbells — simple, functional, and no nonsense. The neoprene coating gives them a comfortable grip and keeps them from feeling slick in your hands, especially during longer workouts or if your hands get sweaty.
The coating also helps keep them from banging up floors or making as much noise compared to bare metal weights, which is nice if you’re working out at home.
Weight accuracy seems fine for general fitness use, and they’ve worked great for things like accessory movements, shoulder work, lighter presses, rehab-style exercises, and general muscle toning. The shape also helps keep them from rolling around everywhere when set down.
They’re not fancy, and they’re not trying to be — they’re just dependable dumbbells that do what they’re supposed to do at a fair price.
If you want straightforward hand weights for home workouts without overthinking it, these are a solid buy.
