I bought this specific blender with concern as there were no comments/reviews. Also, I tried to avoid cheap solutions as I read that they either struggle or have problems. However, it justified me as it does its job and more for its price! It has 2 containers that are durable and have enough capacity. The 600W with the 4 blades seems to be quite capable and can even crush frozen fruits (I haven't tried plain ice yet). It makes juices and smoothies in a very satisfactory texture within 30-45 seconds (don't expect a perfectly smooth blend like the nutribullet promotes). The locking mechanism may require a few turns to "fit" correctly in the slot, but it's not something annoying. Once it locks, its operation starts and you can choose when to stop it. Generally, like in most blenders, avoid continuous operation for more than 1 minute and place the hard/compact products first (along with adding some liquid) to protect and prolong the life of your blender.
