Item was defective but a refund was processed very quickly

Very good quality, very useful - I used to use it with my 50mm lens. That's effect!

Great affordable lens.

Good value, and does the business. Will not produce macro like the dedicated lenses but for the enthusiastic amateur a cheap alternative. Have given it 4 stars as they are a very tight fit and I did think one was 'stuck' but all now work fine.
