Welcome to our forum.
1) They say ants and critters eat and make nests in the full foam spas. IS this true? I can only imagine the critters that can live in an unfoamed spa like a thermospa.2) They say leaks are a costly repair (searching and digging in the foam) in a fully foamed spa. Arent leaks covered under warranty thru HS, SD, etc? Also, outside of a warranty, is it really hard to find and fix leaks? Is your spa's foam destroyed during the 'digging' process?3) What are the benefits of a Thermospa over the competition?4 and last) Can you even wet test a thermospa since they sell factory direct, ie, no show rooms?
