I have been using this keyfob along with an HiRK 433A receiver module. I use it to control my volleyball scoreboard - mainly whilst I am playing. It has performed very well, being used intensively one evening per week for about two hours for the last EIGHT years.
Lately the plastic started cracking and disintegrating, see picture, When you consider I paid about £13 for it and it has lasted all that time I'd say it was excellent value for money and will be buying a replacement shortly.
