The i705 looks great and has a good size, but as someone from the working class, the price of over 6,000 yuan is still a bit high. The X6100 and X6200 are also good options, but they cost around 3,000 yuan. As a parent with young children, I'm worried about my child accidentally dropping the machine. Recently, I saw a machine called MCHF that costs around 15,000 yuan, but only 1,500 yuan. It seems like I've found a suitable machine for outdoor use. Now, I was wondering if anyone has had success using this machine? I hope my friends can help me.
