Well worth the money
Got the cl 110 and liked it that much I upgraded to the 800. Brilliant! The only niggke is it didn't come with the longer leads the cl 110 did but my long fluke leads fit in really well.

Thumbs up
Nice bit of kit

Good but corners have been cut...
When this first arrived I put the supplied batteries in and was met with a dead device & blank screen. After testing the batteries and reinserting them it came to life and has been fine since. Everything worked well but attention should be paid to the manual to fully understand all the settings options. Thereafter it's simple to operate, and comfortable to hold and use. The supplied thermocouple is only rated to180°C although the meter supports higher temperatures. I have a calibrated Testo class 1 thermometer & probes and found the Klein was consistently reading 1 to 1.5°C above that of my calibrated thermometer. This was the case using the same probes on both devices. I won't be using it to measure temperatures except when it's all I have to hand. The meter defaults to the farenheit scale but you can change that to default to celsius. The display backlight is bright and clear but the led work light is a bit dim. You might find yourself using the backlight often as some of the icons on it are tiny. It's a pity the leads are probes only as the inclusion of hooked and crocodile clip attachments would have been welcome additions, as would the magnetic hanger have been too. Where Klein additionally cut corners is with the case. It's a floppy'ish zipped case with no partitioning or mesh separators. It would have been nice to see separate compartments for the meter, leads, & thermocouples. It also needed some rigidity as it was flimsy and not well padded. I suppose most engineers will just wrap the leads around the meter and keep it in their work bag instead of the supplied case. The supplied user manual is quite small and could do with being better printed. Do yourself a favour and download the online PDF version instead. It's much easier to read. Despite the obvious corner cutting this is an excellent value Cat4 TRMS Clamp meter capable of both AC and DC ampere readings providing you focus on its core strengths and ignore the minor issues. As such I give it the thumbs up 👍.

Dropped just once from 20 cm and stopped working....
Dropped just once from 20 cm and it stopped working. Worked perfectly until it was dropped. I fixed it but taking it apart and tightening the screw holding the dial selector. Not sure how long the repair will last. Don't but this product.

Stopped working
Klein cl800 just stopped working blank screen tried new batteries in it made no difference, for the money I paid for the item I thought it would last while not less thank a year hardly had much use utterly rubbish

EXCELENTE PRODUCTO
Excelente producto calidad precio para todos aquellos que hacen mantenimiento. Un producto con materiales de buena calidad, se siente muy bien en la mano, el peso es adecuado a su tamaño. Buena lectura en su pantalla, se agradece mucho la buena iluminación en la pantalla y la linterna integrada, muy útil cuando estas trabajando en lugares poco iluminados o cero luz. En su estuche cabe perfectamente el equipo y sus accesorios y un par de pilas extra. 100% recomendable. La entrega fue acuerdo a lo programado. llego en su empaque original y en perfectas condiciones.

RECOMENDABLE
Su uso de momento ha sido a nivel de instalación propia y alguna que otra chapuza, pero su uso ha sido bastante completo, de momento la pinza Amperimétrica cumple su función con bastante precisión y a un precio muy asequible en comparación con otras marcas. Amplio rango de magnitudes. Recomendada 100 %

Features and Comparison
This is a great meter in terms of form and function. The exterior is very durable. The plastic parts seem very sturdy and there is a rubberized coating on the sides as well as on the dial. The dial and buttons are firm and feel like they are very good quality. I'm not an electrician, I flip houses for a living. I have an occasional need for a meter to test an HVAC capacitor, the continuity of a fuse, a faulty breaker or my car's alternator. I owned a Klein MM6000 about a year ago for a very short time. It seemed like a fine meter and worked well but I was hung up on owning a Fluke as they are known to be the best in the industry. I tend to gravitate toward the best of the best when I buy anything as there is so much crap out there. Since I didn't have much of a need for a meter at the time, I returned the MM6000 and started researching Fluke to determine which one I wanted to buy. Needless to say it has been a year and I just ended up with the Klein CL800. The main reason was price. I paid $120 on Amazon for this meter and it's features are equivalent to Fluke's that cost $300-$500. I would say the features contained in this meter are closest to what you would get with a Fluke 375 or 376 which are $329 and $468 respectively. Obviously the most important thing with a meter is that it is accurate. The specs on this meter, according to the data sheets, appear to be on par with many of the clamp meters from Fluke. This meter has so many great and convenient features. First of all it is TRMS. It tests AC/DC voltage to 1000V and AC/DC amps to 600A, and also handles millivolts. It tests continuity, capacitance, diodes, resistance, frequency and temperature. It has a setting for low impedance, it has a flash light, a back light, hold button, min/max, range, and a non-contact voltage tester. The non-contact voltage tester lights a red light when there is voltage present but there is no tone and it works from approximately 6 inches from a power source such as a light switch or outlet. Some of the things I specifically like about this meter are the fact that it has one setting for volts and one setting for amps and you use the select button to switch between AC and DC. This meter will also measure millivolts but there is no extra setting. You simply set it to measure volts and it will auto range appropriately. I also like the flashlight and the non-contact voltage tester. Most of the Flukes don't have either of these features. There is nothing about this meter that I don't like. I will mention a couple of things that changed from the previous models of the Klein clamp meters to the new ones. The previous models included an audible non-contact voltage tester, slots in the rear of the meter for lead storage, the previous models included a bar graph which this one does not, and the included leads are of lower quality and do not come with alligator clips included. These features would have been nice additions to this meter but are very minor in the scope of what this meter does. I would have to say this is a great meter for only $120.

Best all around meter for the price!
I needed a dc clamp meter, i already have clamp meters, multimeters but no dc clamp. I checked at fluke, and would pay the big $$$ for it but after checked at a friend cl800, and all the specs compared to a fluke equivalent meter i don’t see the need to pay more than twice the cost of the cl800. I just recieved it today! The shipping was superfast! I checked accuracy of dc/ac volts and resistance with my trusted fluke 177 and it’s impressive! I have variable power supplies, ac and dc, and the cl800 is as accurate as my f177. I powered a led, at 9 vdc, that trows around 300ma, clamp the power supply wire and the reeding was within 10 ma. range precise to what my power supply is showing, I didn’t expect that from a 200$ clamp meter! I will definitely be able to trouble shoot plc’s digital output signals and devices with this! You just want to remember to zero it right before those small precise readings if you want accuracy. I’m an industrial maintenance electrician and this meter will be my primary trouble shooting tool, for the price, compared to my fluke 323, it has a ton of nice features and is more accurate. So far I think this is the best bang for your bucks you can get out there.
