Are expensive electric bidet seats worth it over a cheap attachment?

Reviewers are split. Owners of premium seats like the TOTO C5 and Alpha JX2 frequently call them transformative, citing warm water and heated seats, while others point out durability complaints (cracked seats, dropping pressure over years) and argue a $30-$50 attachment delivers most of the cleaning benefit. The honest takeaway across sources: pay for warmth and comfort features, not necessarily for better cleaning.
