Whilst there are not only 'cheaper' but also more expensive enuresis alarms available (some excellent, others not so...), the Rodger Bedwetting Alarm is perfectly suited to the more 'discerning/demanding' Parent and Child.
It removes the concern that some parents have regarding the personal intrusiveness for the child, of wearing a sensor unit directly inside the underwear (some of which can be very hard, large and uncomfortable - this being the main reason why a child will ultimately refuse to use an alarm).
The Rodger Wireless Enuresis alarm is 'kinder' for the older child that is 'aware' of their body, as older children are understandably much more likely to be embarrassed and feel awkward about having to place a sensor into their underwear near to their 'personal parts'.
Equally, parents can't help but feel concerned for their child's safety, going to bed with a wire leading from their underwear up to their neck area. Whilst I have never heard of a child suffering any form of harm from the wire - these are natural parental concerns that needed addressing...... hence the creation of the Rodger Wireless Bed wetting Alarm, which DOES NOT use a separate sensor, but instead, a micro-wire that is built into the special cotton, machine washable underwear and a small transmitter which connects to the OUTSIDE of the pants and NO connecting wire.
