Boogie Board Writing Tablet

UPDATE 5/21/19: I raised this to a 5 star review because of the great customer service I received from Kent Displays, the makers of the Blackboard. I contacted them via their website and explained the problems I experienced. After providing them with the serial number and pictures of the defective Blackboard, they promptly sent a replacement via FedEx. I am very happy with the outcome. UPDATE: I lowered this to a 3 star review because I have to recalibrate the tablet every so often. After having Pressed the erase button several times during use, after a while, it dims the screen to the point it's almost impossible to read. As if it sets itself to setting number 12, the dimmest of them all! Also, I find that the battery cover is impossible for me to remove. I tried using a quarter and it wouldn't turn to the open position no matter how firmly I pressed down to turn. It messed up the slot and the quarter now slides out when I try to press and turn. I hope that I never have to replace it because I am struggling to get this thing open. ORIGINAL REVIEW: I bought this to use as a scratch pad for math. I like to conserve resources and I felt like using paper was wasteful, even though I try to use the same sheet and just erase everything once I run out of room. Anyway, I got tired of having to erase all the time and also having to clean up the little eraser crumbs. This Blackboard by Boogie Board is pretty cool! I can now erase with the touch of a button or spot erase by holding down a button. It's important to calibrate the "exact-erase" feature otherwise it'll look like you're dimming the screen every time you erase something. Setting #5 works well for me. You can find their calibration video on their site. It's referenced on the sheet that comes with it. The pen with eraser that comes with it feels good. I wish the point was more fine because the writing comes out a bit thick. I find that spot erasing by using the writing tip is much better and more precise than using the eraser. It doesn't require as much pressure and leaves less smudging (the exact erase feature simulates eraser smudgings, that's why it's important to calibrate). The only thing that I don't like about it is that when the screen is locked, even though it lets you write, if something scratches the pad or you put pressure on it, it'll "write" or "smudge green" on it. It's not a big deal unless it smudges something important. It comes with 4 templates (grid, lined, blank, & planner). You just slide one on the back and since the screen is clear, you'll see the template you chose. It's really cool that the screen is clear because you can trace diagrams or whatever you want. I'm disappointed that the back of the board isn't able to hold all of the 4 templates. Only one fits at a time and even then, it fits loosely and slides out. I fixed that by making 4 tabs out of packing tape and stuck them at the bottom and lower sides. Now the template is held securely. I can shake it around and the template stays put. It's a great buy! I'm happy to be using much less paper (even though it's been the same 2 sheets for quite sometime. My erasers will appreciate it! Lol 🤣)
