Small compact inexpensive. Screen is the replacement for my old orig. Tots and takes very good place in my small Samsonite laptop backpack. This product is in spite of small dimensions unfolded the same size, yet lighter. Brilliant. The knob is very handy and tight and the shield can be worn well. Even stronger winds has been mastered without problems. Rainwater runs off extremely well and the screen is almost dry after shaking. I highly recommend this product.
