"This is my second kit. I wore the first one out, but I got about 16 months of use out of. The seal is still fine but the foam broke down and started leaking."
"Very difficult to adapt to base, it ripped immediately! Hate it!"
"Nice to have exptras on hand"
"Insert fits well in mask and is easy to install, be sure to watch for eventual cracks in silicone as it will cause air leaks."
