A User of Blocksi Manager Education Everywhere
This review section is very unhelpful, filled with a mix of disgruntled kids trolling and empty praise. So here's a detailed review from a mature student whose school has used BMEE for years:
It is very unreliable.
It's good at blocking a specific URL- it's nearly impossible to get into a site that it's targeted -but it's horrible at choosing which sites TO block. For example, a couple years ago my school, which had already been using BMEE, decided to start blocking videogames. I don't know when exactly they made this decision because I, a regular gamer, didn't even NOTICE. And I didn't for 2 reasons:
1. I'm used to random sites being blocked: I don't know the cause of this, but BMEE will (seemingly at random) add new sites to their block list. It can be anything; something as random as an author's homepage, as trustworthy as the state congress' contact info, as educational as an online physics simulation, as essential as Google Drive, and even (yes, even this happened once) the school's own website! My classmates/instructors are used to the frustration of blocksi getting in the way and thwarting approved activity
2. I could (and can) still access games just fine: If you have slightly more persistence than a 4-yr-old, getting around blocksi is laughably easy. I've seen dozens, if not hundreds of sites completely slip under its radar. And certain specific blocking options, like filtering-by-keyword or blocking Youtube videos, just don't work at all!
In the above examples, I'm only talking about videogames; but I can safely hypothesize that if I were trying to access something actually dangerous or obscene, BMEE would be just as ineffective.
Blocksi does come with a lot of features, meant to give teachers a lot of control. But I have almost NEVER seen a teacher use them; For example, yes, a teacher can kick a student out of a website, but why would they? They're in the same room as the student; confronting them directly is easier, faster, and doesn't escalate tensions the way forcefully kicking them would. Most teachers either have easier and/or more comfortable ways of doing things already, or trust their students as responsible enough to not require such harsh monitoring.
Yet after several years, my school has worked with BMEE enough that it's now pretty good at it's job. But it's been a long, drawn out battle, and this beast is not fully tamed. I would advise trying for another software; this one can work, but it's more trouble than it's worth.
