Customer Reviews

Nice product ,but poor long term reliability
I had bought an earlier model preceding w4100,the 4000 .It broke down two years into use requiring refurbishment and again it failed.When I spoke to productline[Tim] manager,he told me the failure rate is about 3 percent in 4000 and about 2 percent in 4100 and increases to above 3 percent in 3 years. When I told him about poor hardware reliability,he told me iphone does not last more than years,which is not a reply expected from him.He is defending the product high failure rate.The stethescope works well only when it works.For a premium product and for a biomedical product ,the hardware reliabilty and quality control is very poor.Annual life cycle cost of this product is 162.5 Dollars excluding batteries.I recommend people to buy at their own risk

Littmans electronic stethoscope.
Excellent acoustics. I got this because I was losing some of high frequency hearing capability. This stethoscope really helped with that. As I teach also I wished to record sounds and play them on my computer. The software only works on windows xp and I will need to get a separate computer to work with it as all my computers use vista.

Great teaching tool
I've had the 4100ws for about a year, and am very pleased with it. The sound quality is very good, and it eliminates some (but not all) background noise. I have found it to be an outstanding teaching tool. The recording function is very easy to use, and the IR transfer works well. IR transfer to a desktop works only on windows XP at this point, which is frustrating for us mac users. You will need access to an XP machine to pull the recorded clips off. I often use the clips in presentations. This works very well, but you need to know that regular computer speakers won't be adequate. On normal speakers, the clips won't sound much like the murmur you are trying to present. I paired mine with a Bose sound dock, and the murmurs sound quite real when played on that. This is a GREAT way to teach med students, nurses, RTs, etc.... when you come across infrequent auscultation findings, you can record them and later play them for your colleagues so that everyone can gain some experience from the unusual presentation. I also love the 'slow play' feature, that lets me slow the playback down to 1/2 speed, to make murmurs easier to evaluate for students. My only complaint is that I can't transfer recorded clips directly to my mac.
