I need a new pair soon mine have just a out had it. Not sure what brand I should get.
Where are you?
Any basic wiper will work - the factor is keeping them fresh.
In CA, NV, AZ, and other dry climates - change them every six months.
Everywhere else? Change them annually.
I buy mine in bulk (handy having a supply chain,) and get 5-6 pair at a time. Every 2-3 years. For what I pay for one
wiper locally (which is invariably fancier than you really need!) I can buy 2-3 pair of something that will work just as well for just as long, and keep them fresh and new.
It will also help if you throw a good coat of wax on your windscreen. A good hard paste wax - it works better than Rain-X (I use Rain-X for paintball goggles and such - I wax the windows on my vehicles.)
But, change them with the guidelines above, and you'll be okeh.
