The hardware you are able to buy here is amazing! The case screws where too short in my package and I had to use longer ones. But all together the hardware is working really well.
The software is buggy, a little bit old, unstructured and confusing. For example you have to disconnect the power supply after changinng the wireless mode. Without you will get lots of trouble. But, thats okay... I thought. I decided to just use an other ESP32 software (Tasmota https://tasmota.github.io/docs/). The main idea was not so bad. But it was a little bit difficult to get a usefull documentation of this hardware. It was possible with a lot guessing and trying... Could be documented much better!
Physically: The board is nicely designed. One major flaw is the quality of the green screw jumpers that are really fragile. After a couple of screw/unscrew they already start to let go.
Documentation: Overall it is good. Level of English is OK, I would rewrite some sentences to be clearer but that's just my opinion. The part about the configuration pad (P1/P2/P3) is really confusing (at least, to me) and could lead to damaging the board.
Communication with the seller: We all hate newbie questions... I get that. Yet, I think, as a seller, you need to get over that and be patient with potential buyers. Although the few questions I asked were answered by the seller I had a clear feeling that I was being a pest to him just by trying to enquire about the board and the shipping. I guess dealing with all customers' questions must be tiring after a while...
Shipping: I chose the standard shipping option. I did not expect it to take 4 and a half weeks to get here in France. I ordered from Bosnia, Slovenia, Poland, and Russia before via economic post and it took maximum of 18 days. That is not the seller's fault. Yet, "There was an option for Standard shipping and DHL Express too but you picked up this one." and "Also, we usually mark orders as shipped although we take it to a post once or twice a week." were NOT the answers I expected from the buyer when I politely and calmly enquired about the parcel...
Sorry for writing a somewhat mixed review but I tried to be as fair and impartial as possible.

Thank you for the long review. Though it sound to me more like 4 but it got 3 : )
Anyway, i'm very sorry for the shipping, It's pretty unpredictable. Few days ago i had shipping to USA which took only 7 days. Europe is pretty quick lately. But sometimes, especially around big year sales, it takes that month.
Anyway, lesson for me. I don't think i deserved 3* in this case, but again, i did the best i could in this situation.
