The average price is $127.50 (per Camel^3), but it's on sale for $99. There are certainly more premium models available for more, but this one is (IMHO) nearly impossible to beat for the price.
I've been using mine for almost a year -- it replaced a Nexus 7 -- and it's an amazing value for the price. The 1280x800 IPS display actually looks really good; by contrast, I thought the same resolution was underwhelming on the 10" Zenpad. 802.11n wireless performance is good; I've never had problems with my connection dropping. It's certainly not a premium tablet, but it performs really well. I use it for video, web browsing, E-books, and mobile games. Works well with wired or wireless (Bluetooth) headphones. It's cheap enough that if a kid breaks it, it's not the end of the world.
Both front and rear camera quality is weak, especially in low light, so you might want to skip this if you were hoping to use this for video chat.
The description lists that it comes with Android 6.0 (Marshmallow), but it actually will upgrade to Android 7.0 (Nougat)
. Asus has been really good with security patches, too. While typing this (seriously), I got upgraded from the July 2017 patch to a Sept. 2017 patch.
The only annoying thing I've noticed is that the MTK chipset is prone to excessive logging; I'm not sure what triggers it, but it'll start dumping hundreds of megs of audio logs every now and then. (I just open the File Manager app to delete the mtklog directory and reboot the device.)
Also, it doesn't support multiple profiles, but it does offer a kids mode that you can use to limit your kids' screen time. The Asus skin isn't too bad, but it's ever more unobtrusive after you upgrade to Nougat. You also can replace the launcher with your favorite. (I'm running Nova Launcher.)
Consider buying a case (and maybe screen protector, too).
