Way too many errors for a test as important as Step 2 CK. Each chapter I find errata that is not listed on Kaplan's official errata page for this book. For example, page 82 states that, 'intraaortic balloon pumps contract and relax in sync with the natural heartbeat', which is the exact opposite. IABP's are counter-pulsation devices intended to reduce afterload and increase coronary perfusion through retrograde flow by inflating in diastole. I have debated not using this book and switching to something else for board prep. If anything this provides some background which you can heavy annotate with uworld but be careful of the amount of non-corrected errors. It could cost you points on the actual exam.

I purchased these spoons when my vet prescribed a few meds for my dog that were tiny measurements - smaller than my usual kitchen measuring spoons.  If accuracy is important, definitely seek some other measuring spoons!  These are not accurate...at all.  First of all, the spoons are not labeled with actual measurements.  Rather, they are labeled with the words, "SMIDGEN," "PINCH," "DASH," and "TAD," which is not helpful, but the seller has listed the measurements in the product description, so I created little labels for each spoon to know their measurement.  After a couple weeks of my dog on the meds, I felt like the dosage wasn't quite right, so I did my own investigating, and sure enough - they are wrong!  What they claim as 1/4 tsp ("tad") is actually 1/8 tsp; what they claim as 1/8 tsp ("dash") is not an actual measurement - somewhere between 1/8 and 1/16; the 1/16 tsp ("pinch") is the only one that is correct; and what they claim as 1/32 tsp ("smidgen") is not an actual measurement - somewhere between 1/16 and 1/32.

Other than the incorrect measurements and lack of useful labels, these spoons are as described and work for my use (now that I have verified the measurements).

Purchased the RE300 from T.E.Dep. and was shipped a unit with a dry probe.  Unit provided inconsistent and unreliable readings.  T.E.Dep. refused to take it back (was at day 45 from purchase) so they brushed me off with the "no returns period" statement and pointed me to the manufacture to get it replaced.

Contacted manufacturer and was shipped a replacement probe which turned out to be even more unreliable than the one it was replacing.  The replacement unit gives readings all over the place when sampling the same solution over and over.  If the probe is left in the sample, it will give a reading of 0mv after about 3 minutes.

Contacted manufacturer again (Frank) and was given a "that's interesting" response when I explained the results I was getting.  He forwarded me to Tech Support where I ended up in voice mail.  I called right back and the lady who answered the phone made arrangements to send me another replacement.

If the 2nd replacement works, I'll adjust my rating accordingly.

Just received the replacement of the replacement and it too is absolutely unreliable.  Soak in distilled water (or tap) for 10 minutes, turn on, swish into solution to be tested, wait 1 to 3 minutes for stable reading.  Reading never stabilizes and removing the probe, turning it off and back on again and into the solution gives yet a different reading than the one just before it and it is off by over 50 Mv.

The unit is made in china and I'm betting that the age of the probe having traveled that far may have a lot to do with why it doesn't work.  It may be simply too old.

I'm going after a refund now.  I'm sick of wasting my time.  When I shell out 100 bucks for a probe, I expect it to work.

This product did not give an accurate reading at all.  Took 3 readings in a row and each time the readings were different.
This is unreliable for serious conditions.  I bought this based on reviews, very disappointed.

I clearly had strep. White striations on the tonsils, swollen lymph nodes, fever, soninordered this and one-day shipped it so I could test the rest of the family.

Firstly, it wasn't a McKesson that arrived. It was something from China. And I tested myself twice and both with negative results (I was tested at the doctor one hour before and it was positive)

Please don't waste your time or money or risk your health by buying this. It wasn't accurate. Just go to Walgreens clinic for $89.

The research in this book has a lot of inaccuracies:  misassigned spouses, incorrect children, incorrect dates.  If you use it, beware and check EVERYTHING with local vital records.  Don't bet your life on it!

Not accurate.  See attached photo.
I purchased 6 digital thermometers and compared their readings.
This was the most 'off' thermometer.

These test strips are totally inaccurate. I wish I had read the reviews and I would NOT have purchased. I thought I just had a bad batch but if you look at reviews you will see what I mean. It read that I was low on salt (2), added a bag of salt and it went to (3) added another bag and it went to(4.6) added another bag and it said (5.2) Turned on salt system and it said HIGH SALT. I Started to doubt results so took pool sample to pool store and it was 50000+ ppm. Drained 1 foot of water, replaced water, filtered used another brand of strips (My Salt Pool sold on eBay) and it is still reading (7) this morning. I am going to ask for a refund since this test strip has cost me time and money. DO NOT BUY THESE STRIPS. IF YOU DO YOU ARE CRAZY.

This hand held detector was AWFUL!  We put batteries into the detector immediately after we received it, turned it on and it instantly started smoking!  We were trying to exchange it and because of our busy schedules and a 30 day return policy we are stuck with a detector that doesn't work.  Really disappointed!!!

I purchased this gauge for use in breaking in one of my nitro engines. This gauge is wildly inaccurate, and a complete waste of one's time and money. I got varying degrees of measurement, most of them claiming that my engine was running at almost 400 degrees; this is simply not possible. I recommend anyone looking at this product, to please look elsewhere.

Very inaccurate.  Reads extremely high compared to Salt system and Pool service company.

This Battery Internal Resistance Tester Is Complete Rubbish!!  You should be completely a shammed of yourselves for ever letting this product pass thru quality control.  1st thing is when switching selector switch over to ohms the LED indicator shows a 1.  2nd problem is the readings are over triple of what my other 2 high quality Battery Internal Resistance Tester's read.  3rd problem they are erratic and never stabilize the readings.  Complete RUBBISH!!  A Complete Embarrassment To The Electrical and Battery Community.

I bought this with two different calibrating fluids, 342 and 1000. At first it wouldn't turn on, but after several tries it did. I checked its reading in the calibration fluids. For 342, it read 330, for 1000 it read 700. Not acceptable. While I was testing it and calibrate it, the meter turned off by itself and I could never get it to turn back on.

Very disappointed in a unit that can't work long enough to test and calibrate out of the box,. Now I wonder if my old TDS meter that died after very light usage was accurate at all. Definitely not worth buying. Guess I'll be searching for a better brand.

Not accurate.  READS 8 PSI high compared to two other brands.

Waste of money and a possible safety hazard created by underinflation

Hot temperature readings are increasingly inaccurate, only registering a reading of "Hi" after a certain point (WAY below the advertised temperature threshold).

Heavily iced water reads at 45F.

Product was tested straight out of the packaging.

Ain't nobody got time for this!

This is horrible!! I just began to use it three weeks ago during a assessment. I am so upset I can't return it! I am a nursing student and I can't use this blood pressure cuff. It constantly deflates for no reason. It almost contributed to some doing badly on a clinical assessment. Luckily I didn't have to use it!! The worst!! Do not buy!
