Our favorite water pick for traveling is down to just $69 from $99

The Waterpik Cordless Advanced 2.0 Water Flosser, a popular choice for travelers seeking a fresh breath and clean teeth, is now available at a significantly discounted price. Amazon's Big Spring Sale has slashed the price of this top-rated travel water flosser from $99.99 to just $69.99, representing a 30% reduction. This deal makes it one of the best value options for those looking to enhance their oral hygiene on the go.

The Waterpik Cordless Advanced 2.0 Water Flosser, model WP-580, has earned its reputation as the best travel water flosser due to its unique combination of portability and effective cleaning power. Unlike many cordless models, this device offers a robust flossing experience that can keep up with the demands of frequent travelers. The flosser charges fully in just four hours using a magnetic charging base and boasts enough battery life for approximately four weeks of regular use. This means that it can easily go the distance without requiring a charger, making it an ideal companion for long trips.

One of the standout features of the Waterpik Cordless Advanced 2.0 is its waterproof design, which allows users to use it in the shower. Additionally, a water plug ensures that the reservoir remains sealed when not in use, keeping it clean and ready for travel. The device features a ~7 oz. reservoir that delivers roughly 45 seconds of flossing per fill, which is more than enough for most people's daily routines. If needed, a quick mid-session refill can be easily done, ensuring that users can maintain their oral hygiene without interruption.

The 360-degree rotating tip of the Waterpik Cordless Advanced 2.0 makes it easy to reach even the most inaccessible areas of the mouth, providing a thorough and effective cleaning experience. The package comes with four flossing tips and a travel bag, making it convenient to carry and use on the go. Furthermore, the device carries the ADA Seal of Acceptance, which is a testament to its safety and effectiveness.

At $69.99, the Waterpik Cordless Advanced 2.0 Water Flosser is not only 30% off its original price but also offers unmatched value for money. It is an excellent choice for anyone looking to invest in a reliable and efficient travel water flosser.

In addition to the Waterpik Cordless Advanced 2.0, Amazon's Big Spring Sale also features impressive discounts on electric toothbrushes and teeth whitening products. Philips Sonicare models are seeing some of the deepest cuts, with several options priced 30 to 40 percent lower than their original prices. The Aquasonic Black Series Ultra Whitening Toothbrush stands out as a budget-friendly option, with its price slashed nearly in half.

For those interested in teeth whitening, Lumineux strips are the highlight of the sale, with both one-month and three-month kits available at discounted prices. These peroxide-free and enamel-safe strips provide a safe and effective way to achieve a brighter smile.

In conclusion, Amazon's Big Spring Sale offers travelers an excellent opportunity to invest in high-quality oral care products at significantly reduced prices. The Waterpik Cordless Advanced 2.0 Water Flosser, now priced at just $69.99, is a standout deal that provides a reliable and effective solution for maintaining oral hygiene on the go. With its portability, long battery life, and powerful cleaning capabilities, it is an excellent choice for anyone who values a fresh and clean breath while on the move.

A simple way to get more value from metrics

We spent one day 1 building a system that immediately found a mid 7 figure optimization (which ended up shipping). In the first year, we shipped mid 8 figures per year worth of cost savings as a result. The key feature this system introduces is the ability to query metrics data across all hosts and all services and over any period of time (since inception), so we've called it LongTermMetrics (LTM) internally since I like boring, descriptive, names. This got started when I was looking for a starter project that would both help me understand the Twitter infra stack and also have some easily quantifiable value. Andy Wilcox suggested looking at JVM survivor space utilization for some large services. If you're not familiar with what survivor space is, you can think of it as a configurable, fixed-size buffer, in the JVM (at least if you use the GC algorithm that's default at Twitter). At the time, if you looked at a random large services, you'd usually find that either: The buffer was too small, resulting in poor performance, sometimes catastrophically poor when under high load. The buffer was too large, resulting in wasted memory, i.e., wasted money. But instead of looking at random services, there's no fundamental reason that we shouldn't be able to query all services and get a list of which services have room for improvement in their configuration, sorted by performance degradation or cost savings. And if we write that query for JVM survivor space, this also

Context Engineering for Coding Agents

The number of options we have to configure and enrich a coding agent’s context has exploded over the past few months. Claude Code is leading the charge with innovations in this space, but other coding assistants are quickly following suit. Powerful context engineering is becoming a huge part of the developer experience of these tools. Birgitta Böckeler explains the current state of context configuration features, using Claude Code as an example. more…

What does less protein and nitrogen mean for methane?

Does feeding less protein to cows over a longer period not only reduce nitrogen losses, but also affect methane emissions? Researchers at Wageningen University & Research (WUR) investigated this in a multi-year study with dairy cows, funded by the Vereniging Diervoederonderzoek Nederland (VDN), the Dutch Ministry of Agriculture, Fisheries, Food Security and Nature (LVVN), and […] The post What does less protein and nitrogen mean for methane? appeared first on Agriland.ie .
