Any slight pressure placed on top of the case pushes the hard plastic hanging mechanism into the edge of your sound-hole and your fretboard.

Now it is only one pouch that you have to squeeze two packets into connected to a plastic bar (which can scratch your guitar sound hole so be careful) which you lay atop the strings over the soundhole

I noticed someone had an issue with one or more of the packs breaking and leaking, and I can't imagine how that happened ... they're tough plastic.

Now, they have a single pouch setup and a nasty plastic retainer to hold it in the sound hole

The pouches now include two annoying little plastic pieces that you have to attach and detach every time you replace the gel packs.

The loose pouch came with a cheap plastic tube, that is supposed to be inserted into another plastic tube with a slit

The hanging hard plastic piece of the pouch is very long and rests against the edge of the sound-hole on one side and the fretboard on the other.

No matter how I secure it, unless I roll the top of the gel packs into the part of the pouch that's supposed to fit into the plastic securing pieces, the pack sits on the inside back of the guitar and the plastic pieces are loose enough to move around and mar the finish on my guitar.

I have to assume the new hanging design will humidify as well because it uses the same insert (which is why I gave it 2 stars), but the new snap-rod-into-clip-and-hang is *way* less convenient, is a pain to assemble, and the hard plastic creates a real potential for damage to the guitar's finish

The one that now ships in the kit has a strange plastic straw-and-channel system for closing two packets into a single case that then is tucked into the guitar hole and then this rigid plastic thing rests on the strings.

Not only does the hard plastic of these new pieces seem to risk the wood of the guitar, the nature of the plastic is destined to fatigue and fail with more use

It would be FAR better to have a bag like a friend of mine has that is longer, has two pouches and then you simply hang it by the middle over the two middle strings with no need for any or these hard plastic parts

As long as I don't leave the case open too long, the Humidipak seems able to maintain the humidity close to the desired level - not perfect, but not as bad as before the dehumidifying procedure

It has worked well when the furnace is running as well as when the dehumidifier in the studio has kicked in on a rainy balmy day.

If you go through them as fast as I have in the past, they start to get really expensive

Bags should harden as they collect moisture but after an entire summer in the northeast they are as pliable as when first opened.
