Bests & Worsts Reviews from Amazon

If using this, achem, off label, and you're a power queen, you will not be disappointed. It's frighteningly powerful. If it isn't, yours is defective. This is NOT like a wand vibrator that you gently push on your skin. This is a beater. It's meant to pound on your muscles, and it does this well. And relentlessly. I would suggest wearing sweatpants. I have to sit on it to make it not run. On low, it's a pleasant rumbling. On high, it will knock your socks off. If you feel like wands just don't have the oomph you need, this is the thing for you. If you like something that is softer and takes its time, stick with your Hitachi -- this is a whole different animal. -- The heads are screw-on, and it has a big rubber boot right above the head. This is good because it is very hard for it to pinch your skin; Dual head thumpers usually have that problem. Compared to a 'thumper', it has slightly less 'push power'. An example of what I'm talking about: Naipo Handheld Percussion Massager Electric Dual Head Deep Tissue Massager with Heat and Interchangeable Nodes . I did not find this to be a problem, it was just as good at working out knots. I have to sit on it to stop it, so there is ample power for anyone's needs. Thumpers usually come with a somewhat more spongy head, and some are interchangeable. Dual head models are a little easier to work with one-handed, and are usually a little bit heavier. It's a matter of personal preference. The Wahl comes with 4 different heads. There's a similar model that isn't 'deep tissue'. I've used that one before too, and it seems they're identical except for the heads that come with it. Except for the "4 finger" attachment, they're all made of very hard 'impact' plastic. These heads are not the spongy kind. Be careful not to hit bone with it! It will hurt. Especially the pointy head attachment. There aren't any aftermarket head attachments offered, so what comes with it is all that can be used with it. A lot of these corded massagers have had a problem with the cord coming loose and causing a short or fire hazard. The Wahl has a very sturdy rubber connector at the base -- I don't think that will ever be a problem. Trying to use it on the upper back by yourself is a challenge -- I suggest sitting in a chair with a lot of cushioning, and then positioning the massager and leaning back into it for this. Same if you want to use it in bed on muscles. The adjustable speed/off-on is continuous like a volume knob - it's not notched. It's very easy to move and can sometimes rub over clothing and change its speed. That surprised me a few times -- I wish it were a little bit harder to move because of this. It's about as strong on low as high. I have run it up to an hour and it will get warm, but not uncomfortably so. As a theraputic massager, it will definately get the job done. The downsides: It doesn't have a heating head. That's okay for me, as I put a heating wrap on after, but some people may want that feature. The hand grip isn't the best - the plastic is a bit slippery. If it's a problem, grip wrap is easy enough to put on; If you plan on using this after a workout, you might want some.
