Very very super useful item. For 10 bucks, it allowed me to look through my sink drain pipes to find the source of mould. Just be very careful not to get it stuck. Bought 5m but managed to use only 1m due to the multiple bends in my pips. But for the price, good buy ??####[['item', 'Overall#Overall', 'positive'], ['for the price', 'Price#Value for Money', 'positive']]
