Watch out for the servos that are included in that model, the sound will be very loud when compared to the other models available you get what you pay for. Also the higher end models will include free shipping. There’s also a few other sellers you can take a look at.
Expect it to be something like the first few sounds aka “dsservo Ds3225 25Kg” in the first video within this post. Imagine 6 of them moving, then you have to add the other machine sounds on top of it.
The servos included cost about $12 ea, and the “silent” ones are about $33 ea and you need 6 of them, so do the math a good one should be about $275 while the cheap servos are around $150 usd.
