The main constraint is patience. Each grit run can be 2 weeks in duration and a learning curve in itself. You Tube offer assistance that would have been manor from heaven when I first started so take full advantage. Everything easy when you know how. ### ⭐ Totally unacceptable noise. *by A***E on Reviewed in the United Kingdom on 30 December 2020* I bought this gift for my 5yo granddaughter for Christmas. she was so excited to use it. Imagine her and her mum's disappointment when they went to use it and the noise was like having a cement mixer in their flat-and it has to rumble for 24 hours. no way is this a suitable gift for a child-noise abatement issues would follow suit. we are returning and expect full-refund. BAD-FORM National Geographic, how could you sign off to having your name with this. disappointed kids up and down the country.
