Item did arrive within delivery time frame I selected but seller didn’t communicate when I sent enquiring message so communication could have been a bit better. The item box arrived pretty crushed and squashed but everything was perfectly fine inside. The item itself turns on but I’m not sure if it does anything. I read and followed the instructions but didn’t hear any noise as it instructed that it would do but I will keep observing it to see if it helps. For first use and for the moment I’m fine with it!
