I've used it enough, but I'm going to quit using it today. To begin with, my account has been hijacked two times! It was also stressful and exhausting to set up my account. Because of the very slow process, I have to read the instructions every time I wish to transact. There is also a lack of user awareness, which frustrates newcomers.
Trezor One, which was released in 2014, has shown to be a selfish wallet since it prioritizes larger transaction fees, lowering the likelihood of ordinary people succeeding in their investments.
My advise to others is to not enter Trezor without first obtaining financial stability and assistance.
