Hello all. I'm quite new to RC electronics, and looking for some cheap ESCs to start playing with (most other stuff I should be OK with). There seems to be a dizzying array of brushed ESCs out there, but these caught my eye:

To my untrained eyes, a pair of these look like an OK setup to start out with, at least for figuring out the basics. I will be using (don't laugh) Lego 9 V motors so 2s LiPos should be fine. They also look like a new item, since they have no reviews. For barely a fiver each I'm tempted to just get some and try them out, but wanted to ask the experts in case I'm missing something obvious (likely).

Anyone used them before? Anyone have any thoughts?
