Question about Weber Home Svl40

Can other buyers screw in the locking screw (no. 9 on page 3 of the instructions) or is our product incomplete? Thanks in advance :)

Of course, you can also use the fan for the bedroom. It is best to switch it on before going to bed and let it run for a while. With an ice pack in front of the fan, it cools the air even more. The noise level is 58 dB
