I found the product made of exceptional quality it was solid and felt durable.
I found the suction caps strong (so strong it's hard to take off the tank).
I lost one egg during the process however that could be due to flow as it was my first time, I was learning the ropes.
This is the first tumbler I have used however atm, I can't think of anything better to use. It's a great product, may be not the cheapest however in the long run it will pay for it self.
Not much more I can really say or add however if you have any question please don't hesitate to ask
