The mid-term reply will require the use of PPT. Practicing the internship will also require the use of a large number of PPTs. The key point is that the signing aunt sent a two-dollar Jingdong gift card.
Do not talk to you, first buy links
Deli 2801 Rechargeable Portable Page/PPT Page/Laser Page/Wireless Presenter Black Red 99 Yuan Jingdong Direct Link 
The packaging is a bit simple. Oh, big brother, you can be twice as expensive as other page flippers. This packaging is too sorry for the audience.
Able to produce a laser pointer pen, from a small effective products give me a reliable impression, which is why I'm willing to spend more money to choose this page flip, the biggest reason is of course because of the value of the
Red laser, it is said that the brightness is not as green? But the laser is just my secondary requirement. The green laser's page turning style is too few, and it's expensive.
Long instructions to die, throw away and lose
Charging line, although short, but good workmanship. The point is he can use to pass data! ! It is not a big deal for such a device that only needs to be recharged to be equipped with a USB cable for data transmission. However, it is enough to show that it can handle the product well or not. I have always had a good impression on him, like this one.
On the left is the power switch, damping sense of good Oh, pushing a sense of heavy, not embarrassing, but a little bit of texture buzz. Goodwill +1
The enter and tab buttons on the right, these two buttons estimate that I will never use, because Xu Wei teacher said inserting hyperlinks inside the ppt is a wrong thing. (PS I think that Xu Tong's PPT tutorial is full of dry goods. I recommend you have PPT, you can go and see)
At the bottom, the laser can't shine on the eyes. OK, I know.
Switch close-up, pushing the texture full of wood
The three main buttons, up and down and laser keys, the buttons are rubber, feel good. The first laser key that I bought must be strongly pressed to use it. The rightmost strip is the status indicator. The charge breathing is full and the button is pressed to light up. Blue looks good.
Usb interface and never use the Enter, Tab button. Usb did a foolproof, pull plug is very compact, inserted into the cry is very crisp. I like it!
Next is Tucao time, this page flipping ass really full slot ah. . .
This mold line, dare to dare to polish it? Zhazhe ah brother! ! !
This gap can still be accepted, but I feel I can do better. By the way, the propaganda page said that there is magnetic attraction. In fact, the magnetic force is particularly weak. It may be to avoid the influence of too strong magnetic field on the chip (I guess the NRF24L01 2.4G chip)
The red laser, I have seen a three-inch laser module... Big Brother next painted the module black. When I saw the yellow laser head, I remembered that I did not sleep for three days and three nights in the game.
Ass is a one-size-fits-all, after the receiver is unplugged, two 90-degree right angles come out straight! ! Zha hand ah, ah, big brother!
The receiver is a bit overbearing. Plugged in with the normal data line will already squeeze.
With the mouse line, it's not crowded but it can be inserted
CZ80. Don't squeeze it in, don't plug it in. When you talk about PPT, you often have to insert a USB flash drive, so you can only copy the contents of the U disk first. By the way, the wide-rooted CZ80 of the laser pointer is a hairy, two CZ80s in length and thickness. For your reference.
Simply open the box to this end, I wish you a happy holiday season. Before you buy it, you searched for Aunt without sunbathing, hoping to help worthy friends. I also hope that all of you will wish me a smooth reply on May 4th.
