Review on Alstar 4 Elements Barlow Multi Coated Optics by Kevin Damndjperiod

i recently purchased this camera accessory and was extremely disappointed with its performance. After i put it to the test the images that I captured were extremely blurry and lacked the clarity that I expected from a product in this price range. The multi-coated optics did not seem to make a significant difference.The only positive thing I can say about this product is that it was made of durable materials, but that doesn't excuse its subpar electronics. Overall, I regret spending my hard-earned money on this product and would not recommend it to anyone..
