I really liked the product. It was worth the price.
These were recommended by a friend. They seem very sturdy but as I have not used them I can't comment on their performance. The black part is rigid plastic while the blue items are firm but flexible rubber. Angle degrees and millimetre measurements are marked.
quality is excellent. highly recommend for sure and the best price! the blue parts are made of stiff rubber which is very comfortable. the black scraper is hard plastic for for the cleaning job. the finish is perfect.
