Critique Construction and Design Flaws

okay i think i got it back together maybe not um i guess you have to have a degree to work this thing um maybe it's supposed to go maybe it's supposed to go this other way so there we go now it goes on there just like that but you can see it's got a push button right here release i'm not sure maybe you could use it on an extension pole well you can't use it on an extension pole because there's no threads so it won't it can only be used by hand this device is going to flip over and this is going to be your edger right here so that's going to um i'm not sure what it's going to do but um how does it walk in place the uh so i gotta say one thing is it didn't come with any instructions so a lot of times i'll review something and people will say you know you didn't use it by by following the instructions um and so here's a little wheel so it's got little wheels on it right here that will guide you along your surface and it's got little brushes if you eventually these brushes will wear out and where do you get new ones um because the place doesn't exist anymore i'll tell you i went to the website after purchasing it and you can't get it anymore this is kind of like a special roller let me see if the core so that doesn't come out so you wouldn't be able to use the roller anymore and i'll show you let me pull some lints out right here so i don't know if you can see that so the roller itself is extremely cheap so that's going to leave lint all over your wall if you don't delent it but here's the problem so i use this thing what was interesting is as soon as i use it on a perfect scenario so they put it in a perfect scenario like on our perfectly a 90 degree wall you're going to see them in these videos and they make like a wall with a i think a door jam or a window and they put a perfect 90 degree corner no texture or anything and this thing is going to ride up against that and it's actually going to paint a line and paint a straight line but that's short-lived eventually when you run into any type of textures any time of bumps any type of humps anything that's not a perfect 90 degree corner everything begins to fall apart eventually how do you load this thing up and not get paint on your wheels and how do you not get paint on these edges and stuff eventually paint starts to build up on this thing and it becomes a big mess and a worthless tool and i gotta say the plastic on this thing is plastic and i'm not a plastic expert but this is something you would even
