I got this for my boyfriend for Christmas and he has used it almost twice a day, every day since. It's very sturdy and durable. Make sure you put it on a stable surface before using. We originally put it on top of our roll-away dishwasher and it was so strong that it made the entire thing shake and move around. IT has suction cups on the bottom to keep it from scooting across the counter though so that's a good feature. I love the auto-IQ buttons. This blender does an amazing job of juicing fruits and veggies. I am impressed with the pulverization of strawberry seeds. I'm not sure why but it doesn't seem to work as well on black berry seeds. Maybe they're tougher? It does a great job with fibrous stuff like apples and celery. I personally like it for my keto diet because I can mix almond milk with strawberries and have a yummy treat. I haven't had an leaking problems with the blade or lid attachments. I will say though, don't put either attachment on too tightly or you may struggle to get it off. It seems to suction itself onto the cup. A few times I got worried that I wouldn't be able to get the lid off. I also find all the pieces easy to clean. Overall, great product! Worth every penny!
