Very solid product
They weren't exactly clear about the shipping process, but the ring arrived and it works exactly as advertised. It is more accurate with tracking my REM than my other wearable.

I purchased the Resvent iBreeze CPAP unit together with the Dynamic ECG Recorder ER1-LW. I received both items in good condition (well securely packed) including all items as advertized and sales agreement. The Resvent iBreeze CPAP has been working flawlessly over the last 2.month. Unfortunately my ECG Recorder stopped working. However, all Kudos to Wellue, after consultations with Wellue support, Wellue immediately replaced the faulty unit. The new unit has been working well for the last 3.weeks. To get better extensive reports on the ECG recordings, you will need the join ViHealth VIP @ SGD 100/year.

I like the product. Works as advertised. Unfortunately order processing was very slow. It arrived late. Also, they process payments through PayPal. I personally don't use PayPal but recieved scam PayPal email associated with this transaction - can't say if this company was at fault or not - so be aware the problem exists.

Ordering direct is easy and fast and always a good bit less expensive than Amazon. We use the finger monitor to track a health issue and the ring style is much more useful than the end of finger clip. Unfortunately we have had the device slip off a few times and actually lost one because of that. It gets used a lot and provides peace of mind.

El dispositivo es bastante cómodo e interesante de utilizar, a mi me esta situando bastante con respecto a mi apnea. Algunas cuestiones a mejorar, teniendo en cuenta que mi sueño es muy delicado: - Yo he tenido que ponerle una cinta negra en la pantalla de la pulsera porque, para mi, ilumina demasiado y me desvela. -Da puntuación de la noche en base sobretodo a si ha habido más o menos desaturaciones de oxígeno pero no tiene mucho en cuenta los movimientos, por lo que puedes haber pasado una mala noche de sueño superficial con muchos despertares conscientes y como desaturas muy poco debido a que casi no hay sueño profundo el dispositivo puntúa muy alto, por ejemplo 8 o 9 y para ti ha sido una noche de perros pero entiendo que es un aparato sencillo que hay parámetros que no mide y es normal. Debería tener más en cuenta el gráfico del movimiento. Por lo demás yo estoy muy satisfecha con el mío

Fonctionne très bien après quelques difficultés à se connecter à mon portable. La traduction du menu en français est très mauvaise, c'est même ridicule. Je l'utilise que pour la prise de tension.
