Has anyone bought any of these for either yourself or yer kids? I'm currently under pressure to buy 3 for my kids. Recommendations on where to buy would help as there seems to be a big difference in prices. On https://shopee.co.th/*MB*Outdoor-Hum...711.1714966833 they appear to be a 6th of the price as on 'Aliexpress' or 'Lazada'. https://www.aliexpress.com/item/Free...pm=2114.search
