I've had this Musa 510 for about 20 hours now, here is my initial review:
It is a nicely carved harwood cylinder, has an Arizer Solo/Air mouthpiece o-ring at the top, screen in the middle, and metal heat shield around the coil.
O-rings have about the right ammount of tightness, thee mouhpiece goes in and out well and holds tightly in place with minimal wobble.
The RDA has Two o-rings and the wood is slightly carved to hold on them even tighter.
So you can't emove it just by hands or accidentaly.
It has to be screwed on something to get a grip on to be able to separate the RDA.
It can deliver thick hits if you take the wattage up a little.
But it certainly seems to have some learning curve to it.
As I would expect, it hits colder when you pull fast and hotter when slowly.
So I can get thick clouds at high wattages while also pulling fast, but I'm also risking combustion there.
On lower wattages where accidental combustion doesn't happen for me it can be tricky to get the vapor going and he cloud are not as impressive.
I suspect some of the combustion could also be caused by hotspots.
The original coil forms a tight and wide ring of 3 loops and it delivers more heat to the sides than the center and has 2 hotspots on opposite sides (one bigger).
I've tried to make my own coild that would distribute more heat to the center...
...and I think I've overdid that goal. My coil has a hotspot in the middle and is too cool on the sides.
I'll try something inbetween the next time when I get some more SS wire. I've used all I got for this coil.
Or I could try reshape the original one a little.
So far this is a nice and simple 510 vape with a great compatibility with Arizer stems.
And relatively easily user-replaceable coils.
By that I mean you can easily access the coil and you can make one just with some tweezers and a vaping SS wire.
But it's not really easy that any idiot could do it. You have to know what you are doing when making a coil for this.
It can take some work a lot of tinkering to get it right (mostly to make sure there are no shorts and that it's perfectly secure and centered).
Also solving the hotspots can also be challenging, I'm still yet to succeed at that.
That together with the learning curve and those typical manual on-demand temperature swings - I think this vape is more for the advanced vaporists than newbies.
Also remember that I've only had this for 20 hours and I'm still in the process of learning and making the right coil.
My impressions can still change.
Here is a picture of the original coil (left) and the one I made (right on the RDA), and my drawing of their heat/hotspot profiles below (the rotation can be misaligned):
Here are pics of the wooden body without RDA from above/below (standing on a glass jar to make it see-through):
