Co2 diffuser

[williamng]

Anyone use denerele, ada or bioplast diffuser? Why are they price much higher than the taiwan brand. Any difference in performance?

1st and foremost... you are buying the brand! You pay for ads and marketing (Besides that, quality counts too)

The same question: Why do some companies like Nike, Sony, Apple Computer command primium prices?

What I gather is that the pricier diffusers tend not to clog and provide longer trouble-free service (with steady stream of fine bubbles that dissipate into the water quickly). One cheap diffuser I once used had a cloggy membrane that produced horrid large bubbles. Nowadays I use reactors (plugged into my Eheim outflow pipe) which dissolve the Co2 fully.

While not always true (sometimes there are big brands which are really crappy - think famous soft drinks or fashionwear/furnitue that is all design and no function), premium brands are usually priced high because of what they deliver (in terms of service life, reliability, after-sales and other intangibles). All too often, I think many people fail to look beyond the raw price into the total cost of ownership for a product.
