Alright so I've had both these for roughly 2 months now and used both heavily, I am now exclusively using the KR8, Not only has it performed better but the 510 doesn't work at all anymore! So heres my rundown on why the KR8 is the winner
510
Purchased from HC, got the manual kit w/ 2 standard batts, 2 atties, and 20 blank carts. Shipping from China was much faster and cheaper than from the US so they earned bonus points for that! Once I got the primer fluid out the 510 worked great and produced huge clouds of vapor, I ended up using it for dripping and only around the house because the carts suck, the battery life was originally decent but degraded quickly to the point where i couldn't charge them fast enough. After 2.5 weeks the first attie started to fail and produced little vapor, I soaked it in vodka and hot water rinse, let it dry a few days and it worked great again, or at least another week till it permanently died. Attie #2 worked great till about 4 days ago when it died and could not be resurrected. All in all I like this unit when I'm sittin around and have the time to drip, flavors seem washed out and TH isn't great but dripping with it is great for DIY liquid just to do sampling. With the luck I'm having with Atties and Batts for this thing the KR8 is turning out to be way cheaper! I have ordered 2 mega batts, 2 new Atties, and a passthrough, and I'll give it another shot.
KR8
I have 2 ultimate Automatic Kits from V4L and auto and manual batts from Health Cabin.
Much more solid and better batteries that last much longer per charge, produces great vapor if you can hit the sweet spot between too full and too empty. I love my KR8 because I'm a rancher and I'm always on the go bouncing around in a tractor is not good for dripping! I can take 2 batts and 2 carts and I know I'll be good all day. Flavor is much better and throat hit is much stronger. The carts have been great, I have a wide variety from V4L and have enjoyed all of them except the virginia. I've burned a few carts but thats cause I vaped them dry. I even washed a few out after 5 refills and used them again! I got a 50 pack from HC and they've been great too. Of the two kits I got from V4L the first had a broken passthrough and the second has a non working battery. I have emailed them and they'll be replaced with my next order. The batteries I got from HC worked great at first but after a few charges the cut off time has decreased on both the manual and automatic, down to 4 seconds and then the light flashes 3 times, not sure what that means but its annoying as hell. My batts from HC have 2 large holes where as the V4L have 4 small holes. Also I noticed you can activate the auto switch in the V4L with a magnet, in the HC the switch is made from something non magnetic. So I guess all batteries are not made equally!
I think the KR8 is much better, After 2 months its still working great, and I still have plenty of Carts, some carts have lasted me a week, some for 1 day (Vaped dry) I used it much more than I did the 510 which did not survive the 2 months!
