Two years owning two of these Ccell Palms, and NO complaints.
I found the 1 gram carts clog. The .5 gram carts don't.
Having said this, not all cart manufacturer's have the same quality. Trial and error until you find your brand.

My CCELL Palm worked well for the first few months but it clogs and does not pull oil through nearly every single time. Hot off the charger or days later, it does not work. I’ve contacted CCELL for a hopeful exchange.

Honestly I was stoked to get this battery since it has such good reviews but i’ve never had a battery that makes my cartridges clog more, it’s basically every single time. Regardless if it’s an easy or a hard unclogging, one thing is certain: you’ll get distillate in your mouth. I wouldn’t recommend it. (I think the issue has something to do with the magnetic holder rather than the traditional screw)

Very convenient, no problems to date.

Love my CCELL palm, dont go anywhere without it.

I purchased my CCELL Palm about 4-5 years ago as a way to try a 510 thread vape cart, as the CCELL Palm was the least expensive battery at my local dispensary. Now, almost 5 years later, my CCELL Palm is still working great as long as I keep the battery cleaned w/ rubbing alcohol. One major thing I have found, is that there’s virtually no clogging issues if you use a 0.5 gram vape cart, but I have noticed that users have had clogging issues when they use 1.0 gram vape carts, or any larger sized vape carts. So, this vape cart battery seemingly lasts forever with little to no maintenance (besides a quick cleaning every now & then), AND tends to work best with 0.5 gram (1/2 gram) vape carts instead of using a full gram (1.0) vape cart, or larger quantity carts.

I've had my CCell Palm Pro for a few weeks. I use a 1g cart and fill my own carts. So far, I've had no problem with it. It's easy, convenient, and discreet. We bought 4 more.

Love this, vape, it's very convient,gives me the perfect hit, I've had mine for quite sometime, Never had any clogging problems, They're great to take into the non cigarette smoking bars, they are allowed.
All in All, its a pretty nifty lil vape

My Palm lasted almost a week before it would no longer work. no buttons you just charge it, shake it, draw on it and pray that it works....it wont. Save your money. I would give it up if this was the only vaporizer on the market, of course how would I continue...it doesn't work.
