The Neptune Systems Automatic Top-Off Kit v2 is a simple, standalone, and complete solution for replacing water lost to evaporation. The new aquarium hobbyist has many challenges, but none is more annoying than the chore of adding water, every day, to make up for that lost to evaporation (a.k.a. topping off/up). This alone usually makes the automatic top-off (ATO) device the first piece of automation equipment purchased.
The Automatic Top-Off Kit is designed to not only be super-simple to install and use, but it is unique in the market as an ATO device with three layers of redundant monitoring and water-level control. The ATK does the work for you, while at the same time protecting your tank and your home

- 3 Levels of Safety Protection!
- Two optical water-level sensors (one for water level and one for emergency back up)
- IQ-Fill water run-time intelligence – learns how much water you use at each top-off
- Mechanical float valve prevents water overrun if electronics should ever fail

Watch that's not a Speedy with its own 1970s racing heritage from the same group that owns Omega
Beautiful watch with its own heritage, yes it's at the upper end for a Tissot, but the high caliber movement used other brands like Omega and Longines as well as the superior fit and finish, justify the price of this watch.

What a Watch !!!
It's truly a very good watch, and I’m quite happy with it. Let me break down the reasons why:
The design: the front, the dial, the bezel, the case
It has an outstanding design and looks incredible on your wrist. It gives you that feeling of wanting to wear the all day, just because of how good it looks. The case dimensions are really nice—at 41mm, it’s relatively large but still within the wearable limit. The thickness of the case also helps a lot, since it doesn’t have an automatic movement or a date function, it’s much thinner than other Tissot chronographs and doesn’t feel like you’re carrying a rhinoceros on your wrist. The proportions and the positioning of the subdials give it a very premium feel. Of course, it’s not a Rolex Daytona, but that’s not what you're looking for here. What you’re looking for is something original, different, with a distinct racing look and bold colors, without crossing into gaudy territory.
The movement
I think having a manual movement in this watch is a total win. If you’re considering this watch, chances are you already own others with date functions and automatic movements—and if you don’t, it would pair nicely with this one. This isn’t meant to be a daily watch, for me. It’s a watch for relaxing, going out for drinks with friends, spending time with family, it’s more laid-back, more of a weekend watch. And for those moments, you don’t need to know the date, you just need to enjoy the experience. For daily wear, there are plenty of other options in all price ranges, from a Seiko 5 to a Datejust. The manual movement on this watch gives you a sense of connection to it, something special. It really adds a lot to the experience.
The price
Sure, it’s not a Seiko 5, but for what it offers—a chronograph, manual movement, from a brand with history and pedigree, without being a cheap knockoff of the Daytona—it’s an absolute win. This is one of those watches that adds to any collection, whether you’re just starting out or already have a box full of watches worth thousands of dollars. It won’t feel out of place, and you’ll always find an occasion to wear it.

Good comfort, quality and classy
Size: 8.5, Color: Black/Ivory
’ve been wearing Cole Haan dress sneakers for work and travel, and they strike a really good balance between professional and comfortable. The biggest advantage is how lightweight they feel compared to traditional dress shoes. Most styles have sneaker-like cushioning, so you can walk or stand all day without your feet getting destroyed.
The design is also versatile and look polished enough for business casual outfits but still casual enough to wear with jeans. They work especially well in office environments where a full formal shoe feels too stiff or outdated.

New Favorite Work Shoe
Size: 9.5, Color: Black/Ivory
These Cole Haan Grand Crosscourt Daily shoes have quickly become my new favorite work shoes. They’re incredibly comfortable right out of the box, with just the right amount of cushioning and support to get through long days on my feet.
I love that they look sleek and professional while still feeling casual enough to wear anywhere. The build quality is top-notch—durable materials and solid construction that make them feel like they’ll last a long time.
Overall, these shoes strike the perfect balance between comfort, style, and practicality. I can honestly say I look forward to wearing them every day. Highly recommend for anyone who spends a lot of time on their feet but doesn’t want to sacrifice style.

Well Made for price and style
Size: 10.5, Color: Black/Ivory
Great fit and very flexible. I also recommend buying shoe savers when purchasing this product. To help with toes wrinkles. The pair itself is stylish and very comfortable. Any purchase of this product will be greatly satisfied.
