Mám, užívám teprve asi týden

Mám, užívám teprve asi týden.
Zatím spokojenost, jen si člověk musí trochu zvyknout na ten zvětšený průměr. Jedenáctka mi pasuje na oba ukazováky i prostředníky, tak to zatím střídám.
Sportovat moc nemohu, pro invalidy na vozíku sporty žádné NICEBOY zatím nemá. Kroky to nějak počítá od máchnutí rukou. Placení jsem zatím neměl jak použít, jsem na zahradě, příští týden je vyzkouším v lázních.
Ostatní funkce jsou podobné jako na hodinkách SAMSUNG.
Tak ahoj a ať se prsten dobře nosí a používá

Výborné je že si nejdříve mohu vybrat přesnou velikost a pak už není problém zadat v objednávce.

s prstenem jsem spokojen, jak s platbami, tak s monitoringem - kromě jediné věci:
spánek to měří jen cca od 22 do 8 hodin (dle odpovědi na dotaz v niceboy chatbotu), takže např. odpoledního šlofíka to nezaznamená...
námět pro softwarové inženýry - a co lidi pracující v noci?
sizing kit je výborný pro základní orientaci při výběru, ale prsten (mi) sedí trošku jinak. rozhodujete-li se mezi dvěma velikostmi, z vlastní zkušenosti radím: prsten objednejte větší.
případná výměna za jinou velikost naprosto bez problémů.

Ahoj, tady Niceboy,

díky moc za zpětnou vazbu! 💛 Jsme rádi, že jsi s prstenem, platbami i monitoringem spokojený.

Postřeh ohledně měření spánku a lidí s jiným spánkovým režimem určitě rádi předáme dál našemu produktovému týmu jako námět do budoucna. 😊

A souhlasíme i s tipem ohledně velikosti, pokud někdo váhá mezi dvěma velikostmi, i my doporučujeme sáhnout spíše po té větší. Prsty totiž během dne mohou lehce otékat a prsten pak může být těsnější.
