Works perfect have been ablto.balance the flows of my VMC easily with this product.

Package arrived undamaged for ONCE. Lol wth VEVOR put fagaile labels on things! They costs PENNIES IF THAT! ITS LITERALLY LIKE one RMB! OR LESS! =D However I do love their products and their great customer service and speedy response times! When the products arrive intact from the lack of labels on the packages and depending on which courier you get depends on if you package makes it especially if its fragilr or electronic and not in a bag when they knownits raining and they leave ot on your porch but where the rain can get it and yku porch has a roof and dey spot so yeah thats just the couriers (The individual) ones fault dor that stuff However they are always good eith helping out and I see many other customers reporting the same issues and having to wait extra time for their replacement and or refunds like batteries delivered with holes on the casings like a bullet with the things like hiw does that happen?
