Great Prices and Great Experience
"I’ve purchased two TVs through Greentoe, and both experiences have been excellent. Best prices I could find anywhere, and both TVs were delivered right to my door without any issues.
My only mistake was forgetting that Greentoe offers a lot more than just TVs! I recently purchased applioances elsewhere and afterward realized I should have checked Greentoe first.
Greentoe will definitely be one of the first places I check before making a major purchase. Let's get the word out, and let the free market dictate prices. Craig Barton Scottsdale AZ"View article

Extreme 4, my thoughts.
[This review was collected as part of a promotion.] I got this speaker to use whenever and wherever I need a great sounding portable speaker. I chose this one because of its looks and the claims from JBL that it’s water proof, dust proof, has a replaceable high capacity battery, and sounds amazing with AI Sound Boost. I’m not sure what AI Sound Boost is but it must work because it really does sound amazing! Smooth deep bass, clear midrange, and bright crispy treble. It really is tough too. The first day I had it it fell off the tailgate of my truck and you can’t even tell! I think my only complaint isn’t with the speaker, it’s with the JBL Portable app. I wish it allowed connecting other types of speakers on Bluetooth to play at the same time. Not that many people can afford 2 JBL Extremes. As far as the speaker goes, A+, ⭐️⭐️⭐️⭐️⭐️, 👍! Good job JBL!

Best speaker I've ever owned
I bought this speaker last year It's still hard to wrap my mind around it being waterproof, but this is also the best speaker I've ever owned. I've never been unhappy with the JBL product ever before 🥰

Xtreme upgrade!
This is a whole new level…. I bring it in my car with me sometimes 🤣 the bass is so intense, it’s super crisp with the custom equalizer in the app.. I previously had the Charge 4, and this blows it outta the water!..

Very versatile speaker with great build quality!
[This review was collected as part of a promotion.] The JBL Xtreme 4 is a great speaker for taking to the beach or a picnic, or to just chill in the yard. The shoulder strap makes it a cinch to carry to wherever you are going. The fact that it is waterproof it makes it a great beachside companion. The sound is amazing it has great bass and highs, and on top of that you can take your phone far from it and it still be connected. Also I love the ability to have up to 3 devices connected at once, add in the fact that it has a built in phone charger makes it a very versatile device. One downside is I wish that it came with some kind of protective case.

Pretty sweet!
Second jbl speaker purchase. Sounds great, connects every time. Decent battery life (also, battery is replaceable, which is a huge plus.)
