Update:
I've been running into tolerance issues with these resistors. Here's an example: A 680k resistor reading at 734k. On the high-side of 1%, this resistor should be reading at 687k. Now if the product stated 10% tolerance, we'd be alright.
I'm also not a fan of how flimsy the leads are coming from the resistor. Looks like the adage "too good to be true" may hold weight here.

Update:
I've gone through the tedious task of measuring each of the 86 values in this set and here are my results:
470 ohm 2% variance
1.5k ohm 2% variance
100k ohm 2% variance
270k ohm 2% variance
470k ohm 3% variance
330k ohm 10% variance
680k ohm 10% variance
5.6M ohm 30% variance (only one of the resistors read this high, the others hit 1% as expected)
The 2% variance, while out of spec, shouldn't be a concern. The 330k and 680k, however, are way off. One of the 5.6M resistors read a whopping 30% off. I'm wondering if there's quality control issues from this batch.
Joe has offered to replace the sets that are out of range. I appreciate this greatly. It is more important to me in dealing with a business to see that the business cares about its product than getting a faulty item. In this case, I'd like to see the new batch arrive with the thicker leads as promised and with greater QC. Also, again, higher wattage sets!

This resistor kit is a good value for the electronics hobbyist. I looked at several electronics catalogs and hobby sites before ordering this item. The kit provides a great range of precision(1%, metal film)1resistors in a convenient and well marked package. The 1/4 watt rating is fine for most digital and many analog projects. I prefer this box with individually labeled resealable bags to a cabinet of resistors because it takes less space. The resistors are small, so the color code markings can be a bit hard to read. If, like me, your eyesight is not perfect, a multimeter is a useful way to confirm the R value.Best Deals for Joe Knows Electronics 1/4W 86 Value 860 Piece Resistor Kit
the package has resistors from 0 Ohms to 10M ohms with accuracy 1%, .25 Watts rating , good enough for most of the work you might need. cheap price, high accuracy good deal.Honest reviews on Joe Knows Electronics 1/4W 86 Value 860 Piece Resistor Kit
I'm colorblind. I work and tinker with electronics, and it is often difficult for me to discern the color bands printed on through-hole resistors. Many resistor kits do not individually label resistors, and expect the user to sort them. It is very nice that this kit individually labels each bag of resistors!Find helpful customer reviews and review ratings for Joe Knows Electronics 1/4W 86 Value 860 Piece Resistor Kit
I got this kit because I've recently become interested in electronics. One day I realized that the little selection of resistors that I got at RadioShack didn't cut it.This kit is so incredibly convenient. The first thing that I did when I got it was to sort my existing collection of resistors into the bags. They are labeled with the value, so this was really easy.
Some things you should know about these resistors:
* They are the "blue" kind. Not necessarily a bad thing, but it does it make it a little more difficult to read the color codes because the blue background provides less contrast.
* They are 5-band resistors. The box has a great little chart for reading 5-band resistors. If you can read 4-band resistors then you will have no trouble with these. Why was this necessary? Some of the resistors have values that can't be expressed using the 4-band system.
* The leads are just a little bit thinner than you would find on a resistor that you bought from RadioShack, or a similar store. I personally don't care. They are still 1/4 of a watt, but the leads aren't as thick as the resistors that most beginners have become accustomed to.
I highly suggest that you buy this kit. If you ever need to build an oscillator, it will be important to have the right resistor values. Same goes for voltage dividers.
With that said, I have two suggestions for future versions of the kit:
* Please include some empty bags with blank labels so that we can make our own bags if we have some strange resistor values that didn't come with the kit.
* Please include 29k resistors. They are important if you wanted to make a phase-shift oscillator (search for it on Wikipedia)
P.S.: Joe, if you ever make a capacitor kit that matches the quality of this one, I will buy it in a heartbeat.
