A review on Amazon for a vacuum brake bleeder that the reviewer obviously liked says something like "so I threw my leaky Motive brake bleeder in the dumpster".
TBH, none of the DIY/consumer-grade bleeders, whether pressure, vacuum, or whatever, can be expected to be good, durable tools.
The Motive is a glorified garden sprayer/DIY project in easy-to-buy/use form, and like every cheap plastic pressure vessel I've used, will likely leak at some point.
At least they offer replacement parts if you don't feel like cobbling up a repair yourself.
They're ok when they work, but if I had to yank out my Motive more frequently than every couple years (with some trepidation each time as to if it will fail in some fashion), I'd give consideration to biting the bullet and getting something better.
In function, I think I actually prefer the Gunson I used before, which is pressurized from a tire, since it was easier to control,
and release pressure. It also wasn't stupidly bulky, and the hoses didn't twist and fight me, like the Motive does, because I didn't opt for their fancy metal swivel cap.
But it, too, had leaks, which the importer dutifully sent me updated parts to help fix, so it did get into a pretty good state for a while, up until where I didn't want to deal with the leaky chuck shooting off the hose anymore, so I got the Motive for cheap when the big online startup store (jet.com) that was supposed to challenge Amazon and Walmart had a great coupon. Only to see it eventually bought by Walmart and eventually dissolved.
I do break down, clean each time, and try to treat them well, but cheap parts are cheap parts.
Unfortunately, it's like buying a garden hose reel, where there's a desert between the cheap junk, and absurdly expensive nice ones that will last.
