| SHORT DESCRIPTION | MRCOOL® 48k DIY 5th Generation 6 Zone Multi-Zone Mini-Split Condenser 230v |
| LONG DESCRIPTION | We’re excited to introduce our new 5th Generation MRCOOL® DIY® 48k BTU Multi-Zone Ductless Mini-Split Condenser, because it’s better than its predecessor in nearly every way. You won’t need the services of an HVAC professional when you’re setting this unit up, because you can do it yourself, which saves lots of time and money! This condenser enables you to heat and cool up to 6 separate spaces equalling up to 2,000 sq. ft., meaning you’d be able to cover an entire home in the completely efficient comfort of a single DIY® system. You can install this system on your own because our innovative, patented pre-charged Quick Connect® line sets allow you to skip the lengthy and complicated process of evacuating and charging the system. These line sets are filled with R-454B refrigerant, a much more ecological and proficient upgrade from the previous refrigerant used in the last generation. This switch helps the system achieve impressive efficiency levels, like 21.8 SEER2 and an HSPF2-4 of 10. These line sets are sold separately. Once you install your system, you’ll be able to explore the variety of ways you can customize your comfort. For ultimate control, you can integrate system operations with the SmartHVAC app, available for Apple and Android phones, allowing you the ability to set schedules, manage modes of operation, monitor your systems all with the touch of a button. The app even enables you to set up integration with Amazon Alexa and Google Home, meaning you won’t have to move a finger to make your home more comfortable than ever. We pride ourselves on having one of the best warranties in the industry on this unit! Once you install your condenser, you’re entitled to a 5 year parts warranty, a 7 year compressor warranty, and, if you subscribe to the MRCOOL® Care Program, a Limited Lifetime Replacement warranty. The MRCOOL® DIY® is the right choice if you want fast, efficient comfort that won’t let you down! |

"It's a promise wrapped in a threat, and she doesn’t know it" ARC
Format: Kindle
I can always count on Bella Matthew’s books to have found family, a strong FMC, delicious spice and to make me laugh & cry in the same chapter. Sweet Temptation is no exception!
Lexie & Lucky have grown up together. Lucky plays pro-football & lives with Lexie’s brother Lincoln. Lexie is back in town, needs a place to stay, insert our favorite forced proximity trope!
Lexie doesn't want a relationship, she firmly believes that's selfish because she has cystic fibrosis and doesn’t want to cause her loved ones pain someday. She’s also the first and only girl Lucky hasn’t tried to chase… There’s wonderful banter & tension and then finally we get “one night lucky.. It's a promise wrapped in a threat, and she doesn’t know it”
I loved Lexie’s mom & Lucky’s sister for standing up for their relationship & dropping the truth bombs those around them needed to hear. Lucky’s mom for telling him, grand gestures don’t mean sh*t, when you take away her right to choose what she wants. If you love banter, group texts, spice, football romance, forced proximity -- definitely recommend this book!
Can't wait to read more of this second gen.

Such a sweet story!
Format: Paperback
Ok, I’m lowkey obsessed with Lucky and Lexie! Why did I wait so long to read this?! The banter between them and all the siblings and friends had me dying! 😂 The yearning and pining these two have for each other 🥰 Lucky knew what he wanted and I loved when he finally decided to go for it! Lexie was such a warrior! I really related to her character. Having a chronic illness isn’t easy and you always wonder how it’s truly affecting those you love. The way Lucky came in and showed her that he wanted to be with her no matter what had my heart melting. I didn’t expect to feel So many emotions with this one! Cannot wait to continue the series!!

I Love Luciano “Lucky” Beneventi
Format: Kindle
Another 5 star read from this amazing author!
Man do I love going back to Kroydon Hills!
I love these characters so much! Since day one with Nat and Ryan! And to continue reading about their kids! It’s the best.
This book was heartbreaking but in a good way.
Being with some one with a sickness is not easy. It really comes down to “in sickness and in health” and lucky was there every step of the way.
Loving someone for the rest of your life.

I finally decided to use Amazon's Kindle trade-in program to trade-in my 2nd generation dinosaur Kindle for some newer tech. While my old Kindle still did work and had been a workhorse for years, the battery was not what it was, it was heavier, and the lack of back-lit light for nighttime reading was overdue for an upgrade.
This Kindle is very lightweight compared to my old Kindle, even with a case (Moko, Origami Slim Shell), which I purchased as an accessory item. It is almost as light as my Galaxy S8+. The touch screen works well, which is another feature I did not have previously. I can say my only complaint here is there is little room on the sides of the case to rest your thumbs when holding the device, which sometimes causes a page turn accidentally while reading. This normally happens when reading in bed, but it's not a huge issue.
The display is easy to read and I really like the paperwhite design of the display. Also, I very much like the device is backlit with a good range on adjusting the brightness as needed. I don't generally read outside much, so, for now, I have not encountered any issues.
I have had the device about a month and have not needed to charge it since my first charging. I usually keep it on airplane mode and the battery is going strong. Very happy with that.
The one complaint I have had with this device - and it is not the device itself, but with Amazon - the charging cable (micro-USB) lacks a power adapter enabling you to charge the device from an outlet. This was not the case with my 2nd generation Kindle as it came with the full cable and power adapter.
Then, Amazon conveniently recommends you purchase said adapter as "official OEM" adapter for Kindle devices for the whopping price of $19.99. This is a complete rip-off, in my opinion. The adapter should come with the device, but if you are going to sell it separately, you do not need to over-charge for it by this ridiculous amount. You can find another generic adapter for a reasonable price. Just be sure to make sure it matches the specs required for charging the device. Booo - bad form Amazon!
Even with the "missing" adapter, I am happy with the product and the value and price paid. I also very much recommend taking advantage of the trade-in program Amazone offers if you can. I was able to get a $5 credit for my old Kindle and 25% off toward future Kindle product. I also pulled the trigger on this sale during Prime Days so the device was further discounted. This was a great time to upgrade and save money.

Worth the money (especially if you wait for a Prime Day sale!)
Digital Storage Capacity: 8 GB, Offer Type: Ad-Supported, Color: Black, Option: Without Kindle Unlimited
I've had my paperwhite for about a month now, so I guess it's as good of time as any to properly review it.
This is my first paperwhite. I got a b&n Nook Color back in 2010 for Christmas, which has served me really well over the years. However, it reached the point recently where it wouldn't hold a charge and so I found myself in the market for a new e-reader.
I was drawn to the paperwhite because it was waterproof and would hold a long charge. I was a little leery about the black-and-white only nature of the paperwhite, especially as my previous ereader was in color, but so far it hasn't been an issue. I used to read comics on my Nook but haven't read digital comics in a few years, preferring print. This might be something someone who does read books with illustrations would want to take into consideration.
I really appreciate the long battery life of the paperwhite. I've had it for about a month and have only had to charge it once (and it had only gotten down to about 48% so I probably could have pushed it further than I did). I've been able to read several books with the battery barely being effected. The biggest draw on battery life seems to be using the store or trying to use the rudimentary Web browser.
I've been very impressed by the light, too. My Nook was impossible to read on in some lights, which hasn't been an issue at all with the paperwhite. I usually have the brightness adjusted to about the halfway point for casual reading, and brighten the screen if necessary. The brightest option COULD be a little brighter, but that's nitpicky.
The device itself is VERY lightweight and portable. I have dvd cases that weigh more. My phone certainly weighs more. It's not too big or bulky to hold; I can easily hold it with just one hand.
The only draw back I've really noticed is that the touchscreen is a little sensitive. Sometimes when I'm trying to scroll through my library, I end up selecting a title I wasn't trying to open. Other times, I might scroll through several pages by accidently hitting my thumb on the screen when holding the device. Buy this is a very minor inconvenience.
Also, I bought the option with "special offers". They in no way to impede my reading experience. The ads show up on the main screen when the device is not in use, or in a small banner along the bottom of the "home" menu. That's it. No ads popping up during your reading.
