Simpson Sirocco series, 350, 450, 455, 500
(Brisbane, QLD, Australia)
This review comes from a repairer and serviceman of clothes dryers, 6 years experience.
The Simpson Sirocco range of dryers are generally fairly good products that will do the job. I do not rate them highly, for a couple of reasons. Some of the components are not built to last more than a few years of normal use. Most commonly, the plastic belt to run the fan will break after a couple of years use. Some people have actually thrown away their dryers when this happens, not knowing that they can fix it themselves for about $12. Another weak part is the plastic hinge cover on the front. An el-cheapo plastic part, when it breaks the door sags and almost falls off. Cost about $16 for a new one. Again, people have thrown away their dryers in disgust, when this happens.
What else goes wrong? I have seen many that have the horrible scraping noise during usage. Mostly this happens when some grit or foreign object (button, hair-pin, paperclip, etc) falls inside and is caught between the drum and the front friction pads. It's disappointing to see the usage of cheap, non-durable and quick wearing plastic parts in the Simpson dryers.
The earlier models of Simpson, going back 15 or 20 years, were much better built. Older Maxidry and Minimax dryers were generally very good and long-lasting, except that they also used the plastic fan belt.
I'm happy to answer your questions on dryers.
