So exited for our trip to Nusa Penida !!

My question now is , Is It worth buying an easybreath mask to explore the underwater world there ?
Is any of you guys already been using one and what do you thing about It ?

Nusa Penida is famous for having beautiful underwater marine life, like Rai Mantas and, as we are going there soon for a few days, I am wondering If the purchase of an easybreath will be worth It .

Since I live in Bali, about 3 years now , I never had the chance to visit this wonderful part of Indonesia and I am super exited about this coming trip. Doesn't It look beautiful ??
