It's a great honor to be a probation officer of Lei Feng again. I beg you to make up. When did I test the whole projector

Well, to get to the point, when I first got SUNFRIEND, I really didn't know what to think of the product's price tag $49.99 (about ￥ 320)

The workmanship and even the appearance are not worth the price I think SUNFRIEND A very big problem of

I also write the evaluation, hoping that others who want to buy or understand the product can objectively understand the product from all angles

I especially don't like to get things and boast that as an evaluator, I should really talk about the product

Here are a few things to explain for the following

UVI： UV index UVA+B=UVA=UVB UVA: long wave black spot effect UVB: long wave red spot effect ultraviolet

The figure above is straight without saying much

Lei Feng is very conscientious. Fa Shunfeng

But I especially don't understand why such a small thing uses such a large box full of foam

The more you look at it, the less valuable it is

A recent photo of the package

There is nothing in English on the back of the package except the "Lei Feng Trial" on the back

SUNFRIEND Naked Photos Personally, I think the product is really not beautiful, and we still need to see the function

When I finished shooting and uploaded it, I found that it was reversed. That's it

The whole controllable buttons of the product are four and eleven indicator lights representing eleven levels

The four buttons are: Switch, set sensor, check button (what are the two values of the check explained above), UV index

Switch: when SUNFRIEND is off, press the ON key to scan all indicator lights from 1-11 immediately

When SUNFRIEND is on, if it needs to be turned off, it is only allowed to press the ON key for a long time for one second. Scanning the indicator light from 11-1 means that it is turned off

Setting button: this is to set the required degree of sunshine

Press and hold for 3s, and then jump backward from 1. You need to set where and where to loosen the setting button

Attached here is a list of usage methods and UV recommendations

Check button is used to check whether the degree of sun exposure on the day reaches the set index. All lights will flash together to indicate that the sun exposure is enough

Let's take a look at the strap. The strap is really made of shit. It's too ordinary. The thread is drunk

What I appreciate about this product is that it can finally break away from mobile phones in modern times without mobile apps

At this stage, the word "smart" must be added to the bracelet, which must be bound to the mobile phone APP

It really needs such independence, not too many restraining factors

This product has a certain value, but it is not enough to mention the price

So the price really needs to be reduced. Under this condition, the price should be controlled within ￥ 80. The sales volume of this product should still be considerable

And this product faces too small a crowd. Ordinary people will not choose such a product that will become a burden on their wrists
