I ordered my unit on June 23rd (very early AM) for next day delivery. My Unit came with firmware 1.22, calibrated late April 2014, All TIConfig mods applied fast and without issue, confirmed thermal images now at 320 x 240! Works great, uses a single cell Li-ion cell in it's battery so you should be able to refurbish the cell in several years if you want. Ergonomics are great, weight is great, really this doesn't get any better. Hard case it comes with with is fantastic, it has foam cut-outs for everything, including accessories that you can buy later (like the independent battery charger and a spare battery). Best thing I've yet seen, a case that takes what comes in the box and the most commonly purchased accessories.
There is however a few things that buyers need to be aware of:
1. Thermal Imagers are supposed to need periodic calibration, how often and the real need is based on usage and expectations. FLIR says you need it every year, this is likely untrue and a ploy to get more money because FLIR designed the units to require FLIR to calibrate them and there is no field or third party calibration (at this time). From what I've read it seems with light use it's anywhere from 2-3 years or perhaps longer. What happens if you don't get it is that spot and temps are inaccurate. Do you care? Maybe not, if the goal of the imager is to highlight hot spots and show you a colored thermal overlay of surfaces and how they compare, that will still work, I'm told the differences still hold true in the image. it's just that the entire scale skews or slides in some way, making actual accurate temp reading an issue. From what I've gleamed as a new E4 owner, if you can live with ~ 5 - 10 Degree F of inaccuracy then you don't care about getting it calibrated. (other reviewers are welcome to add insight if I'm mistaken).
Why am I talking about this? Because FLIR will FORCIBLY update your firmware if you send in the unit to them for really any reason. They refuse to leave it alone and you have no choice. So if you send the unit into FLIR you get a firmware update which (at this time) undoes and prevents any modifications. Now 2-3 years from now the situation could be different. But today, let's just say you don't want to send it in.
2. The unit does a "calibration" (not the same as temp calibration in 1.) every couples seconds which causes the display and readings to momentarily freeze. This is normal and I don't find it very frequent to be considered irritating.
3. USB charging seems to require some resistor values, just hooking voltage to a USB line causes the charge indicator to appear but not charge, I've not confirmed if high-wattage iPad or the like chargers work with this. Included charger is 10W.
4. After modification you need to change the USB mode to include MSD (Mass Storage Device) to get your images out by plugging in USB. I'm not using ANY of the FLIR software (Don't need it and I'm afraid of it tampering with my settings so I've not loaded it).
5. The MSX view isn't always going to be correctly overlaid. I've confirmed this with FLIR tech support. The unit doesn't have a range finder, so it doesn't know how close an object is. You have to go into the settings -> distance option and change it. I find 1 works great for close things and >10 is best for rooms and homes. You have to keep changing it if you care about the overlays looking good. A minor issue in the long run but I had to call to make sure. This setting ONLY adjusts a vertical overlay mismatch, if you have any horizontal issues that is an assembly issue and won't be fixed in software (I'm told).
For the price, if you do the mod, it's a great value. I'm a little concerned about the calibration issue, however that's years off and by then the situation on the firmware may change (downgrades may be possible or the like). If you're on the fence, just buy it! A situation like this won't come around often. FLIR is closing this fast! It's really cool what you can see and the uses are endless.
Until Amazon is restocked (that is they receive a new batch of stock) this (their current stock) may be the last place the get the old E4s at retail prices.
It's the best toy I've gotten in years, you'll love it too!
UPDATE (6/26/2024): I've confirmed on the forums and through my own tests that the temperature accuracy of the E4 isn't great (spot temps and such). Specifically it seems to get cold temps wrong (way too cold). So recheck ANY measurement this thing makes!
That being said, I still love it, for qualitative measurements (comparing areas) it's great, it's poor to bad for quantitive measurements. But again if you're doing quantitative measurements with a thermal imager you'd pay the extra money to get NIST certified calibration and have it in yearly for checkups (for legal reasons in court you'd need this to backup the claim your readings are accurate). So check for specifics but you can trust it to spot temp differences (even minor ones) to alert you to a problem area, just don't take the spot measurement as true temperature.
UPDATE (7/24/2014): This thing still rocks hard but a couple additional notes: 1. The FLIR Tools should really be used (I'm using them from the Apple App store) to improve the downloaded pics from the Imager. It's best to import the pics you want into the tools, resize the window/image to what you want, then use the screen clipping to capture a rectangular section of the image as displayed. I do this for two reasons, first you get a larger, better picture without the FLIR logo and other info normally only given in a tiny Image, and finally you ensure you don't drag ALL the hidden info that's in the picture which contains your serial number into your new image. You can views the pic straight from the imager but I get a better result Command+Shift+4 clipping them off the app. 2. When the battery is LOW but BEFORE it tells you it's low, you'll see banding lines on your video feed when you use PIP mode or no thermal at all. This banding is temporary and goes away as soon as you charge or change the battery. It seems they didn't really calibrate the low condition right so when the voltage starts to really drop the full-color video starts acting up. I've seen this twice and only just before low battery warning goes off. I've confirmed this on some forums that others have experienced this and it's considered normal. So if you see banding, try a fresh battery or charge the one you have, then see if the banding is gone. Then you know it's a design flaw and just change your battery sooner before you get a low warning. I keep finding uses for thing, seriously it's the best thing I've purchased in a couple years!
UPDATE (3/22/2015) - I used the imager to find out where my cat had been peeing. I could still readily see "potty spots" made several days ago. Obviously I'm simply looking for cool spots on carpet, furniture, and landry hampers and knowing there should not normally be spills in those areas. You won't see old, tried, spots. I also can use the imager to generally check my cat's health. If his nose doesn't register cooler than his face or eyes then he's running a fever (no wet, cold, nose). I've also found I can easily see what furniture the cat has recently slept on (new favorite spots).
Finally, my parents have used the imager to track down missing or lost chickens. Chickens show up very well on the imager even in complete darkness.
