Bests & Worsts Reviews from Amazon

I've had the Tahiti blender for a number of years (did not buy through amazon) and have really enjoyed using it, making yummy frosty drinks. Everyone that uses it really enjoys it and it makes a really great addition to our outdoor beach bar. BUT I am getting really tired of having the jars crack and then break in EXACTLY THE SAME place - on every jar. I've included pictures of three jars - but I've had five in total crack/break exactly like this. The picture of two from Sep 2015, the single jar from Apr 2014 and as I've pointed out, these aren't the only three. It's just a matter of time before the two with the cracks break...not happy, not at all. It's been difficult to find replacements - Margaritaville doesn't have them and were totally unhelpful when I was trying to find them. I did find a company that did have one (just one) and so I was able to get the replacement. And when I talked to someone at the company where I found the replacement, I was told they are considering not carrying this product anymore due to the terrible customer service that they're getting from Margaritaville. Overall, the blender itself if wonderful, but due to the fact that : 1) all of the jars have broken or are about to break in the same place, 2) the replacement jars are so difficult to find 3) the customer service is not very good, I would certainly never recommend this particular blender to anyone.
