JK ones are "ok" for the money, they do the job, BUT the suckers are a bit carp
We've used them for the past 2 1/2 years so a reasonable investment. There's a company near us called "van comforts" that do thick outside style front wrap round covers for the front and inner blinds, but they were about £90 just for the front one (mates' rates, he drinks in the same pub) so I opted for the JKs (

) and as long as you remember that you DO get what you pay for and are happy to prop them up in the gorners by the dash.... They're fine, but not the best is what I'm getting at
