I think whether it's good or not is going to depend a lot on your gear and what you're replacing and stuff like that. I see that it says it's a 22k DPS increase for you, which is quite nice, but you need to think about what your CURRENT weapon has that maybe it doesn't and what your goals are.
Like for example, does your current have crit chance? Or Life Steal? Both on higher MPs and in general that's something to think about as you want (at a sort of baseline ideal) 45% Crit Chance with 450% Crit Damage.
Another big thing to think about is the fact it has attack speed and doesn't have a socket. While there really isn't anything wrong with attack speed on a wepaon, you want to look more at the damage range and not DPS numbers. The lack of a socket means you're losing out on the extra (up to 110%) Crit damage from a gem. That, especially with built in crit damage, is a LOT and can maybe give you more of a DPS boost than this fist is. But again, it depends on where you're at gear wise and what you're aiming for.
Personally though... I would pass. 300mil is a LOT for one item, let alone a weapon that isn't "ideal". I'm playing on MP7 right now (could maybe go to 10 tbh but don't want to push just yet) and I'm wishing both my weapons had high Life Steal on them atm. My EHP isn't as high as it could be and that would help offset it a ton.
This Is one of worst mistakes you can do, do not buy that Item.
Instead, based on your profile, with 300m you can do wonders to your gear and not replacing just one weapon.
Get a CC Natalya ring, replace your Inna legs for high vit ones,
Try to get a natalya boots with vit and 200+ dex for a reasonable price.
As for weapons, replace them both, for the Main hand go for a Rare LS+CD+Dex+Socket with atleast 1k dps (60M-140M),
And get a better WKL with 23%+ dmg, 900 dps with either LS or CD that Is to your own choice and playstyle.
I also would recommend to craft more shoulders, bracers and chest , for the shoulders get a higher vit with same stats as you already have and for bracers get ones With your OWE resist or AR, and for the chest you need alot more stats on It overall, more dex, much higher vit, AR, etc..
Do not, I repeat, do not buy that piece of garbage.for 300 mil u can freaking get a sick one hander with DEX CD SOCKET LS and a decent LS WKL and never die and do a lot of dmg.Or just get an EF for Bell builds.
Let me just chime in and say DON'T DO IT! I wouldn't pick that up if it was thrown after me. Terrible weapon, for reasons already stated. Get a WKL. There are no better alternatives out there.
EDIT: didn't check your profile until now, sorry. Looks like you already have a WKL. Good. But put your highest dmg range wep in your mainhand. Your WKL has lower dmg range (NOT the same as dps) than your Echoing Fury. Therefore, your WKL should be your offhand. It won't show on your paper dps, but you will notice it, especially when you remove that Echoing Fury for a high dmg range (slow) wep and put it in your mainhand

Good luck.
