LONG DESCRIPTION
Our new 5th Generation MRCOOL® DIY® 55k BTU Multi-Zone Ductless Mini-Split Condenser is one of the most efficient and innovative units in the industry, and we’re excited to finally share it with you! On top of saving time and money because you won’t need an HVAC professional, this system will give you a good sense of accomplishment because you’ll have installed it yourself! The whole family will be able to enjoy the comfort of this condenser, because it can heat and cool up to 6 different spaces that equal up to 2290 sq. ft., giving you the ability to heat and cool an entire home to your exact specifications using a single MRCOOL® system. The system’s patented pre-charged Quick-Connect® line sets essentially fast-forward the installation of this system, enabling you to skip the evacuation and charging steps and simplifying the entire process. We utilize new R-454B refrigerant in these line sets, which is a much more environmentally friendly and efficient choice. Features like these assist this unit in achieving its impressive SEER2 of 22, and its HSPF2-4 of 10.6, both of which signify that this system will help you save money throughout the entire time you use it. These line sets are sold separately. Once you install this condenser, you’ll be met with a variety of features to help you control your comfort. One of these features is the Smart HVAC app, available on Apple and Android, that allows you to operate your system from the convenience of your phone. Set schedules, manage different modes, monitor energy consumption, and more all without having to leave the couch! You can also set up voice control through Amazon Alexa or Google Home, meaning you can control your comfort without moving a finger. This system ensures you’ll be enjoying ultimate convenience and superior comfort. The warranty for this unit is one of the best in the industry, and we’re proud to have your back. You can enjoy the peace of mind of a 5 year parts warranty, a 7 year compressor warranty, and, once you enroll in the MRCOOL® Care Program, a Limited Lifetime Replacement warranty. If you need perfect comfort but don’t want to break the bank, this MRCOOL® DIY® condenser is your answer!

Only “tough” toy my Doberman loves!
Pattern Name: Octopus
Not indestructible, but last a good long while. Definitely worth the money and lasts longer than any other plush toys we’ve had (which is all my dog will play with). It’s for sure my Dobermans favorite, I’ve ordered probably 10 at this point. He gets the stuffing out after a month or two and we open a new one. He’s picky with toys, either destroys them or ignores them, but he never gets bored with his octopus! 🐙 He sneaks one outside once in a while and the neighbor’s dogs steal it. They love it too and thankfully can’t destroy before I retrieve it.

Great for a Pitball
Pattern Name: Octopus
I have a Pitbull and she absolutely loves this toy. I always wait a while before giving a review. She has had this toy Since the beginning of July and she is still playing with this toy. It does have little holes but it is still going. She loves it. Playing tug of war with her. I also take it and wrap it around her collar and watch her dance around trying to get it out(I don't leave it there long). This a great buy. I also bought and extra one so when this one does finally dies she will have another. The material is strong, The sound is about normal for a squeaky toy.

Cute, but not tough enough.
Pattern Name: Octopus
This toy is cute, my pug loves it, and I like how the legs are strong but the top of the octopuses head isn't tough enough which is worrisome because thats where the squeaker is. It might work out for a smaller dog though.

Fun Resilient Chew Toy
Pattern Name: Octopus
I have a boxer/pit mix and she loves this! I bought it 4 months ago and it’s still going strong so I know it’s quality made and perfect for dogs that like to chew and play tug of war. It has been chew resistant for my girl and she loves the little squeak. I just throw it in the washer when I wash her bed. Great value and a safe toy that’s a good size for a medium to large dog.
