It was cheaper than buying in Korea, so I purchased it through a coin deal on Ali. The product seems to be stronger and more cost-effective than expected. The quality is better than buying from Daiso. I purchased it as a tool at a low price.

The cost performance seems to be the best. The functionality is slightly limited and the buttons are tight. I am satisfied because I bought it at this price.

I bought it when doing freediving. It's working well.

Hahaha. Hahaha. Hahaha. Hahaha. Hahaha. Hahaha. Hahaha. Hahaha. Hahaha. Hahaha. Hahaha. Hahaha. Hahaha. Hahaha. Hahaha. Hahaha. Hahaha. Hahaha.

Purchased for freediving, the 10m depth was marked as 9.4m, and the 24m depth was marked as 22.8m.

Checking the manual~~

Very good value for money...

I haven't used it yet, I've only read the manual. There is a 5-minute safety stop function.

Great value for money~~~~ It's a bit inconvenient to manually dial the menu, but it's quite good.

I bought it to check the simple water depth and temperature, but it seems to have no practical value. It's a waste of money from the manufacturer. I'd rather not buy it.

If you turn S2 slowly, it won't be recognized. I'm not sure if it's a malfunction, but I'm just using it. The sensor has an accuracy of approximately +- 15%. Considering the cost performance ratio, it's at a good level. The diving program is good.

I need to test the diving function, but the temperature function is more accurate than expected. Of course, when parked, it shows much higher temperatures due to body heat, but when left for more than 10 minutes, it shows quite accurately. However, as shown in the picture, the compass function is extremely inaccurate. Using the compass correction function makes it even weirder. I want to exchange it, but it's inconvenient because I have to send it back.
