Good value

Not the greatest construction material, as it seems easily breakable versus flexible, but for the price, can't complain. Great fit and exactly the look I was looking for. A bit big when folded down to pack but makes a great extra pair of sunglasses to walk the dog, leave in the car, etc.

They do the job!

These glasses may be cheap but they make all the difference in the sun. I try not to touch them too much during the game/practice so they can last longer. For the price, it is a decent product and I recommend it.

value for money

Good value

Very comfortable, lightweight and pretty clear for the price. Bought 2 pairs for each car. Makes my long drives on those sunny days more comfy. I also enjoy these when playing golf or tennis, as they provide excellent grip even when I'm sweating.

Do exactly what you'd expect

Comfortable, protective and cheap as chips

icon-circle-checkmark verified purchase

These are much better than expected and are now my go to sunglasses because they were so cheap. Cycling wise they do exactly what they are intended for keeping bright sunshine out of your eyes and protecting your eyes from flies and loose dirt and grit. They are also great for driving.

Perfect for what I want

Wanted a pair of sunglasses I could leave in the car & these are just what I need.

Can't go wrong with these bargains

Come on now folks. £4.99 for these! They are very comfortable and light. 100% UV filter. They fit my quite large head perfectly. They can't be beaten for value for money. I bought the sunglass and clear nightglass versions and I could not be happier. You don't have to be all precious about them either, just go and buy another pair!

lasted 5 days

These literally melted apart, in half, when I took them off after 5 days of use. Terrible quality plastic. Returned fir a refund,

Great value but they don't last

I've had about 8 pairs of these now over the years, they are great for a few months and then the arms inevitably break off as the hinges are fairly weak. Cheap and cheerful.
