bahut accha kaam kar raha hai
pehle dusri mesh use karti thi par wo bekaar ho gayi thi rust pakad ke. phir ye automatic wala try kiya. sabse best baat hai ki isme bimetal coil hai jo garmi sardi ke hisab se khud hi open close hota hai, koi switch ya power ka jhanjhat nahi. ab basement me mold ya damp rot ka darr nahi lagta aur keede makkode bhi andar nahi aate. delivery was fast too.

works good for dampness
my colleague suggested getting this after i complained about crawlspace moisture and stuffy air under the house. fixing it into the standard opening was pretty straightforward since the size matched fine. box was a bit crushed on arrival but the metal piece inside was safe. glad it doesn't need any electricity and adjusts itself based on weather changes.
