The product has been received and appears to be in acceptable condition. However, configuring the application is somewhat difficult. Additionally, the pressure gauges and oxygen indicators do not seem trustworthy.

The battery has a short lifespan.

It has a long-lasting battery, however, the screen's plastic is easily damaged.

I got here earlier than expected, which is great. It's a present, so I haven't used it myself, but the packaging is good.
