I thought about hoarding those myself. However I sold all my apex gear off with my last tank and decided I don’t want to support a company building crap. I’d probably feel differently if I still had a big collection of apex gearThey usually are reliable, but stuff happens, lol. Most EB4's & EB8's in service have more trips around the sun than any eb832 thats in service.
I have one EB8 in service that hasnt reported amperage in prolly a year now, but its 10+ years old and still switches perfectly (had to replace a few TRIAC's about 4-5 years ago).
The second EB8 is prolly 8 years old (orange model) and one EB4 is about 5 years old now.
I'm quietly hoarding eb8's and eb4's as they seem to outlive the 832's by a large margin and they have become (EB8) or will become (EB4) unobtainium now.
