Door timer closer/opener

Hi there we have just bought a new 8 X 4 tongue and groove shed with a pent roof for the hens and as well as changing the felt roof for bitumen corrugated sheets for ventilation and keep red mite at bay etc. We want to fit a door timer what is the best door timer to put on my shed???
It's not always the dearest items that are the best for individual needs any help much appreciated thanks max

We have the chicken guard.  It is good.  Battery life is about a year.  It lasted 18months before it failed as somehow water was getting in.  Contacted them and sent it to be repaired but they replaced it foc.  Well impressed with this company.

Hi Snow White thanks for the info maybe give one of them a try. Where did you buy it from?? Thanks max

We have the other one sold by flytesofancy. Think it's called VSB. We use it with the aluminium door they also supply.  Absolute godsend and wouldn't be without it to be honest.
The girls soon get used to it and make sure they are in before it shuts up for the night, and in summer they are literally up and out at the crack of dawn, hours before we are!
Expensive, but worth it.
