Vinyl is officially back. People are hearing the proof behind the initial "retro" excitement: that records really do have a richer sound. And if you haven't switched to old-school records for serious listening, it's a new golden age.

Why? Because quality turntables like the Altec Lansing ALT-500 are finally available to a market other than rich audiophiles.

This unit comes with everything you need to start playing: A stylus cartridge, 45 RPM adapter, auto stop feature and two built-in hidden speakers.

But there are some definite upgrades for modern listeners in terms of output. You can transmit sound to your own speakers through left-right RCA jacks. It's also compatible with Bluetooth technology, so you can use your wireless speakers or headphones. You can even stream in reverse, playing music from your own device through the ALT-500's speakers.

The Altec Lansing ALT-500 Turntable is already half off the retail cost of $150, but you can take an extra 15% off by using the online promo code BFSAVE15 - for a final price of $63.74. Read the rest

Between all of our apps, streaming devices, Bluetooth speakers, and energy-sucking decorations, paying for utilities each month can be...brutal. In fact, the average household spends roughly $70 a month on the water bill alone. That number might not seem terribly significant, but when you add it up, that's $840 a year — a pretty significant chunk of cheddar, and that's just for one of your many bills. Pair that with the fact that water conservation is becoming increasingly more important, (especially in areas susceptible to droughts) and being conscientious of your water use is, quite frankly, more important than ever.

That's where Flume comes in. This easy-to-install smart water monitor pops right onto your home's water meter and tracks your water use in real time. You can check in on your use through Flume's companion app directly from your smartphone, which constantly gathers and reports the data back to you. If there's a leak or damage detected, you'll instantly be notified so you can quickly resolve the issue. Flume breaks down exactly where your water is going, so you can figure out how to cut back in areas where you're over-using it and save big on your monthly water bill. And, if you've already got a smart home or speaker setup, you can ask Alexa about your water status, use, and budget.

Keep tabs on your water use with the Flume Smart Home Water Monitor and give the earth and your wallet some relief. You can grab it now for just $169. Read the rest

A typical security camera can give you peace of mind. But that might be offset by the nagging feeling that it's watching you, too.

Sous vide cooking: It sounds fancy, but it's actually one of the easiest and most reliable ways to cook. It's the reason why many restaurants are able to put out delicious dishes with a consistent flavor.

All you need is the right equipment, and that hasn't always been available to those outside the resto crowd. Now that the secret is out on sous vide, gadgets like the Curtis Stone Sous Vide Cooker & Beverage Chiller are letting home chefs prepare their meals in a whole new way.

Sous vide is French for "under vacuum," and that's the secret to the consistency.

Clamp the cooker onto the side, select your temperature on the LED display, and wait. It's that easy to get your entrees cooked evenly and all the way through, the same way every time.

With a simple switch, you can even turn this one into a beverage chiller for impromptu party coolers. Best of all, the Curtis Stone Sous Vide Cooker & Beverage Chiller is available now for 20% off the retail price. Read the rest

The more you use your computer, the more it becomes possible for others to use it too. Where there are anti-virus systems, there are hackers looking for a way to get around them.

That's why it's important to get software that doesn't just passively scout for viruses in the background. The folks behind GlassWire have the right idea, with a service that offers both protection and extensive monitoring that will enable you to make sure you're the only one logging on.

Certainly, GlassWire's firewall is an effective defense on its own. But what the software really does well is tracking. It monitors things in your network activity by app and geographic location and notifies you whenever a new app accesses the web from your system. It keeps tabs on any network activity that occurred while you were logged off and keeps an eye out for known threats and unexpected file changes. And, it lets you see all this info in an easily digestible visual format.

It even helps you use your computer more effectively by alerting you to possible bandwidth overages, and lets you clear your internet activity at a moment's notice.

Best of all, it does all this for up to 10 devices. Right now, you can pick up a three-year subscription to GlassWire Elite for a full 89% off the list price. Read the rest

That's where services like Readitfor.me can be a real life-saver, giving you the meat of self-help or business books in minutes rather than days or weeks.

The current library has over 300 titles and is growing at around 100 additions every year.

Summaries are accessible as animated videos that distill the big ideas and water-cooler facts into bite-sized chunks that you can absorb over a quick lunch, coffee break, or lazy commute. That's a ton of time freed up to actually act on all that great information.

There's a number of plans available, but you can get access to them all on sale now. Pick up a 1-year subscription for $19.99, 5 years for $49.99, or a lifetime for just $99.99 today. Read the rest
