I am sorry to say I bought a pair of Rain-X Lattitude wiper blades today. They were the most expensive blades I saw at the store. The clerk highly recommended them. I asked if they were compatible with my 1989 BMW 735iL and I was told that they were. There was no Rain-x chart in the store so I used an Anco chart. It suggested 24 inches for both the passenger and the driver side. So I proceeded to ATTEMPT to put on the passenger side first. The instructions were pitiful. There are maybe eight combinations of adapter mounting and no real way to tell which one I needed, I could rule out the pin bayonett and P&H styles, but I didn't know if I needed the samll hook, large hook or the I&L/PBT style. So I guessed I needed the small hook installation. When I tried to put on the passenger side, the blade was still loose and the blade extended over the windshield by at least an inch. So I guessed I must need the large hook installation. I attempted to remove the preinstalled connector and the instructions for doing this were vague at best. But I managed to click it out. I saw that there were no real instructions for installing the Universal adapter and after a half an hour of trial and error I was able to get it mounted. But when I tried to mount the blade with the universal adapter I realized it would never fit and that I must really have had the small hook. So after some more trial and error, I was able to replace the pre-installed small adapter. I was then unable to get the blade to work because it remained very loose on the arm and too long for the window. So then I went to this Rain-x site and saw that unlike Anco (which fits BTW) you reccomend a 24 inch blade on the passenger side and a 22 inch blade on the driver side. Well I had not even tried the driver side, but the driver side will likely not fit either if I follow the website reccomendations. And there is another issue! The arm on the BMW has a U shaped flange. The Rain-x blade does not clear this flange. So even though the website specifies certain sizes, thhe Lattitude blade just never will work. Tomorrow, if it doesn't rain, I will return the Rain-x blades and get something that does work. This has been a horrible customer experience. So here are the issues in summary:
1. The instructions stink. They are unclear. They lack any details and they are confusing.
2. There is no way to know what adpater is needed and no chart of way to figure this out even with pictures.
3. The picures really stink, both the printed ones and the website ones. One cannot tell where the clips are supposed to be oriented and where the levers are supposed to be. Images are grainy, lack detail and are totally useless.
4. The posted size information on the website is different than the competitors and the competitors information is correct for their products.
5. The Rain-x size information is dead wrong for the Rain-x products.
6. The Rain-x application chart says the blade will fit on a 1989 BMW 735iL wiper arm and it can never fit because of an interference issue with the flange mounted on that factory arm.
7. When a customer calls the support number, they get Shell and not Rain-x and so it is confusing. I actually dialed twice because I thought I must have dialed wrong the first time.
8. If a cusotmer calls the hotline for help, he/she finds out that the support line is closed after 5 PM so no help is available. Also, the help number printed on the instructions is different than the number listed on the website and Option 2 on the printed instructions does not work when you call the number.
I am compeltely disgusted with Rain-x as a company and the amatuerish way the product is presented and the amatuerish way they present themselves to customers.
Rain-x should really be embarrassed.
