    É um bom aparelho, mas peca na hora de ver as mensagens. Tu não consegue ver a figurinha ou responder. Não tem como colocar uma foto também, mas pelo valor, é muito bom

  2. R***s

    Sim. O produto chegou muito rápido e bem embalada. Recomendo a loja.

  3. J***m

    muito bom

    Se quiser tela de qualidade e um relógio/smartwatch de respeito pode comprar sem medo. Tela incrível e que chama a atenção nesse Amoled. O Haylou RS4 Plus é muito bem avaliado. Como alguns especialistas dizem: “Se tivesse um Always On Display e/ou GPS seria perfeito, porém seria bem mais caro”. * O Custo Benefício tá bom, tá excelente! Obs.: A pulseira é muito boa e prende sim bem ao punho. Porém, se preferir por mais segurança qualquer pulseira do mesmo feixo do tipo de silicone fica perfeito tbm.

    Excelente calidad , me gusta mucho el reloj, gracias al vendedor que siempre está atento a mis comentarios.

    O aparelho chegou muito bem embalado e super rápido, todo o processo da compra até a entrega levou 18 dias corridos. Estou satisfeito com o produto.

  10. M***e

    Haylou RS4+ is a great watch, superb amoled screen and finish and very good blood measuremensts. The other features are just ok, as it misses microphone and speaker, so it can’t handle calls or music. Haylou app is also good but it uses too much mobile battery even trying different adjustmensts. It came by Hong Kong to SP (Brazil) in only 12 days, without customs or mail taxes, great! So, why only three stars? the product itself is 5 stars, however I ordered silver color and shop sent gold color. My wife accepted the gold color, but the bracelet color doesn’t match well the watch color.

  11. Z***h
