I absolutely love dash and never had problems. Dave (the owner) is cool too and constantly on reddit. He's also on discord if ever you need something.
I have $30 in store credit but there's nothing I want to buy right now.
As for DD & Pulse. I used that for the last 2 weeks. I liked it a lot but you just have to be mindful of the coils, you're using a dual coil build on a 80W.
I prefer using one big coil on 80W -- more flavour and vapor.
The only difference is using 21700 batteries. I upgraded to 20700s a while ago so I didn't need it either.
Here's my pulse, I posted for others before but i'll let you admire it (Canada themed: maple wood & canadian rda):
