I bought this at. costco for $19 says it does about 150 tests. Does it signal me when it reaches 150 tests?

Yes, when you reach the 150 test mark, you will begin to get a flashing "FL" on the LCD display. Please note, this ONLY pertains to that particular model available at Costco. The model for sale on this page is longer lasting, and priced accordingly.

Not that I know of. It simply stops turning on when the battery runs out. I don't think I have reached the maximum yet because my alcoholic son absconds with the testers and hides them.

The only time I asked Amazon for a price match, they said no way.... but hey, you might ask as things may have changed. FYI, Costco's regular selling price on this is $369.99 with a $90 "instant off" savings = $279.99, advertised in their most recent coupon booklet, in effect from Feb 3 through Feb 27, 2011. My experience with Costco is that some of their "sale prices" become their new regular prices shortly after the "sale period". I have found this sometimes true on electronics items such as this.

Yes that is how it works. However yesterday I did a pork tenderloin with it in and after the recommended 20-25 minutes this said it was at 113 when I was sure it was much hotter so I put in an instant read and it went to 140+ right away then I took this out and moved the probe and it shot up to 145 so I'm not sure how reliable it is. Perhaps I had done it wrong but I don't know how. I'm still mixed about this I love the idea of it.

You probably already bought your GPS, but just in case, if you look around you may find the nuvi 650 for a lot less. I just ordered one last week (should get it today) from Costco.com for $299 plus my membership fee of $50 plus shipping and taxes, total $374.

I too noticed this in the beginning. The best way I believe to test is to hold the battery in testing position for around 10 seconds . If it is a dead battery it will start showing weaker signals within after 2-3 seconds. Never go with the initial reading as soon as you place the battery. Hope this helps.

Hey Leon. I haven't done a control test in a long time and my CardioChek still comes very close to my medical blood test. It's been a long time but, as I recall, the instructions seemed to refer to a test strip that I had to somehow purchase BUT that my monitor also arrived with a grey strip that could be used as a control. I have never used anything but the grey, plastic strip and (like I say) I haven't seen a significant difference between the personal and hospital tests, in years. One thing you'll have to look out for. I rarely run a test and my strips sometimes "expire" before I get to use them all. I suspect this is mostly a gimmick to sell more strips. For example, how could a strip be valid on January 4th and then be expired/worthless on January 5th? But in general, I think this is a great device for measuring TRENDS in blood cholesterol and triglycerides.

I don't know. I have already returned it to Costco. I had other issues with it and will update my review.

The "Sidekick" comes with 50 strips. The package says the tester will only work on the strips you get. The one I bought included a testing solution so you can verify the accuracy.

I have used mine several times and it seems to work just fine. I suggest you let it cool between tests.

I have tested two 50 foot cables separately and the results were positive. One of the cable was good and the other one was bad. I also extended the 50 by joining another 20 and successfully tested 70 foot. I can't technically comment for 120 but, check the batteries.

Sorry, I assumed it was what it said. How can we test. it. I get about a five mile range.

It is supposed to detect 25, but I got a clear (light) line on one and then had a quant of 11 later that day, so they are more sensitive than advertised!

It does negative values. When you turn it on, it zeroesI've done that when at 1200', so it reads -1150 when I get home.So I assume it will.

I bought ten and had one that was defective. I think they are "dime a dozen" tests so there are a few defective ones in the mix. It could be you just got unlucky. Also are you testing with urine that is extremely dilute? It may not be concentrated enough.

Thanks for your thoughtful reply. I am impressed with Costco's extra year warrenty as well as their 90 day return policy. I'm thinking that would offset the slight improvement of the 550. But I am relying on those much more technically savvy people to tell me if I'm on track.

No it won't. It requires a smaller amount of blood than others. It has a little "drop" icon that showes until there is enough blood in the stick then it showes dashes until the testing is complete then it displays the result. I had mine tested at my doctors office and it resulted very close to their monitor. They said closer even than most others they have tested. Hope this helps. :)

Karen, The only thing it claimed to do was measure my pulse. It could only do that if I was sitting quietly. It would never register if I had been working out. It died the day after I got it.
