For me personally, it is the perfect pod for 3 very specific reasons (I explain why 4 stars a little below):
1. You can find replacements everywhere. Literally, I have never been to a store that didn't have coils or filters.
2. It has the perfect size for pocket and because you can put it in the mode that activates only with inhalation and deactivate the button, it is incredibly convenient.
3. The most important thing so far, I never suck liquid anymore. 14 years after I started vaping with atomizers from 10 to 180 euros, I always had this issue (obviously in the expensive ones it was minimal but still existed). The idea of the filter was excellent.

However, this does not mean that it does not have disadvantages and for me, the only worth mentioning is the following: There is a big difference in the air holes from Vilter S to Vilter S. I have 3 sets and they all have different inhalation. In one, the inhalation is full of smoke, in one (the red one) it is much airier and in the 3rd it is somewhere in between. So you can easily get 1, like it, and get a 2nd and not like it at all. Nevertheless, it remains my favorite pod and has never caused me any problems.

I have no words for this specific pod.
I am a DTL user with powerful vaporizers like Geekvape Legend 2 with z tank, Voopoo ARGUS GT 2, etc. All good so far, with nice clouds and plenty of flavor.
The problem with powerful vaporizers, however, is that I often feel like I'm bothering others, for example in cafes, at work, even at the beach. And if you're a bit conscientious, you don't feel comfortable, and I have realized many times that my clouds bother those around me.
So, I decided to go for an MTL device for such occasions, without spending a fortune on a second mod, but I wanted something affordable, small, that could fit in my pocket or bag, along with the Legend.
It really saved me. I paired it with a tobacco-flavored e-liquid, a classic Tribacco, and I enjoy it from the first puff.
Pros:
Convenient and aesthetically pleasing in the hand
Nice cigarette-like and quiet puff (the filter, although unexpected, really reminds me of the taste and sensation of IQOS. For those who don't want a filter, there is a plastic mouthpiece included in the packaging.
Very good flavor for a pod
Choice between automatic or controlled puff with a button
Screen with necessary indicators
The battery easily lasts me a day of moderate use, as I vape with the lung device at home.
The only negative thing I can say, as I have only had it for a day in my hands, is that even though it's MTL, I noticed that it consumes a lot of e-liquid. With moderate use, definitely 4 refills per day.
Time will tell its durability and reliability. If I find any other negatives, I will come back and update.
Regardless, it's worth the money and I recommend it to those who want something cigarette-like (MTL), small, convenient, easy, and affordable.
