I’ve had mine for about 6 months, and it does not leak, nor does it clog. I have had no trouble cleaning it, and it seems durable. It’s plastic, and does show smudging/fingerprints unless you clean it thoroughly with soap and water after use, and if you use the device with too small a cup you will have an overflow (I haven’t measured, but it holds more than a teacup… more like a travel mug), but those are my only complaints. I’ve tried it with finings (taken out of a tea bag) and with whole leaf tea, and either work very well — although the loose tea looks nicer when it is brewing. I have seen a similar device at both Distinctly Tea and at DAVIDsTEA in Canada, and I also saw a larger version at Teavana. This one is just perfect for my uses — a full container results in a nearly-full travel mug.
