I bought one of those Aliexpress mesh heads to replace a torn one. Not for an Alesis kit though so I don't know if the sizes actually fit properly, but I bought an 8" one and it fit mine fine (converted acoustic tom). It works ok, but the problem I find with it is that it's very loud. It was so cheap (I paid about €4 postage included) that I thought I'd give it a go, but I much prefer my DIY mesh heads using silkscreen mesh. I don't know about durability either because I don't use the tom I put it on, but it seemed sturdy enough.
