It’s ok for a short period of time.
Meh….the filter is glued at each end versus clamped into the housing like the OEM filter. Will probably get a different brand or OEM in the near future.

perfect fit for my CRV
Size: 26"+17"+B12", Style: J-HOOK
These wiper blades fit my Honda CR-V exactly as described. All three sizes were correct and clipped right onto the U/J hook arms without any hassle. Installation was quick and straightforward, even if you are not very handy. Once installed, they wipe evenly with no streaks or skipping. They are quiet and make good contact with the windshield, even during heavier rain. The rear wiper works just as well as the front ones, which is a nice bonus since some sets overlook that. Overall, this set feels like a solid OEM-style replacement at a good value. Works great and looks clean on the car. Very satisfied with this purchase.
