But not a professional gives an idea better than the Price

At this point I would also like to praise the seller.
One of the lights was damaged (one probably due to shipping), but was replaced in the fastest way.
The set is very cheap, but you can not expect any professional quality!
The tripods can be, even if they are found, squeeze again. Not normally used so much violence but when dealing with the normal parts.
The lamps fulfill their purpose, the screens work fine and make a quality impression.
the wording for the lamps is made of plastic, but solid. Toll solved here is the introduction of the screens.
All in all a very good set for this price.
Packed everything was tidy. So 5 stars for price / performance
