3m and Bosch.

First of all, the influence of the brand alone is enough to occupy a part of the market sales. Bosch brand, affiliated to Bosch Power Tools Co., Ltd., was founded in Germany in 1886 and is one of the largest industrial companies in Germany.

As for the workmanship of the wiper blades, first of all, the wiper blades are equipped with internal steel bars (protective effect), which extends the service life to a certain extent. The second is the use of double elastic steel sheets to make the pressure transmission more evenly distributed. Coupled with the special coating on the surface of the rubber strip, both the quietness and the wiping effect are quite good.

The 3m brand can be regarded as a senior "old player". It was founded in the United States in 1902 and is one of the world's top 500 companies, so the brand influence also exists. The 3m wiper blades use imported rubber raw materials, coupled with a silent silicone deflector, which can provide good noise reduction.

The second is the upgraded metal memory steel bar, coupled with the titanium alloy base specially used for special cars. Not only does it have a longer service life, but the design of the steel claws allows the wiper to better fit the glass, thus The effect of scraping is cleaner.

In general, 3m wipers are indeed better than Bosch in terms of materials (quality), but they are not very affordable in terms of price. The cheapest wiper costs more than 160 yuan, while Bosch wipers The cheapest one is about 50 yuan.

So in terms of cost performance, Bosch wipers are definitely slightly better. After all, the performance of Bosch wipers is good enough. Of course, if your conditions permit or you want better quality, I believe it is definitely right to choose 3m wipers.
