Well I tried Hansa and DHL and I did a couple others I think, but before that I hadn't used anything besides Nucleus and Alphabay. I mean of course I used a lot of the markets that do not exist anymore but currently these have been the main two lately and I guess some other ones have popped up since but I did not know they were being used much.
One thing I noticed that was cool about Hansa is the reviews ask for 'actual delivery time'. Usually you can only see the date when they ordered and who knows when it was actually shipped, so it is cool that you can put that, definitely helpful in deciding a vendor.
On DHL I kinda like how they have one listing for each product, and you put multiple weights inside there. This is definitely a cool idea, but it actually can make it harder when you are searching sometimes. It shows the price for the listing as min-max and well the minimum could be $10 for one vendor because he sells a gram of weed, whereas another person minimum could be $250 because the lowest is an ounce. So in some ways it's not the best but it is a cool concept. Hansa does a similar thing, but it just says like 'other options' or something, and has the other sizes of the same product.
I don't know if any other market has used this, but I miss the thing BlueSky had where it said price per gram or something like that. I don't think it worked one bit, but the idea was there and if it did work, it could make searching a bit easier in some cases.
As long as they have the feature of not running away with my money, they're cool in my book
