The feature text excludes Purobot Ultra and Purobot Max Pro. Confirm that your exact device is supported before purchase. The 5 cm dimensions and 8-ounce weight are listing details and are not clearly explained as bottle or pack measurements.

Customer feedback highlights a pleasant smell and good perceived quality. This may matter to buyers sensitive to the scent of a litter-area deodoriser, but the feedback does not establish how strongly or how long the refill controls odours. The product is listed for compatible devices, so confirming fit remains essential.
