If you just tap the Boingo (or a Snappi) on the diaper without attaching it properly, then it is not on correctly and you won't like them. If you use it properly, it will work correctly. When you get a new Boingo (or Snappi Fastener), you need to break them in properly before using them. Stretch the new Boingo several times hard to stretch and soften up the new Boingo. After it has been initially warmed up like this, it becomes softer and more flexible. Then when you attach it to the diaper, it has some stretch to the material and it is easier to attach properly. Attach it so the teeth are grabbing the fabric. The teeth need to grab the fabric with a slight bit of tension on them to hold in place. If attached properly like this, then they stay put. ALWAYS use a cover over your fastened diaper no matter what brand of fastener you are using. Let me say this again. Do not use fasteners coverless. Use a diaper cover over your fastened diaper at all times. Keep fasteners out of baby's mouth (of course). Store them in something when not in use to keep the teeth safely stored away. A little paper or plastic baggie or a certain slot or compartment in your diaper bag, for example, will keep them safe and prevent them from getting lost.

Prefolds and Workhorse hold up very well to diaper fastener use. Flat diapers are better with pins than fasteners, but some choose to use fasteners (Boingos or Snappis) with their flats anyhow. Over time it can take a toll on the fabric of the flats since the grabbers do go into the fabric to hold them. To minimize wear on the fabric, always pull the fastener out to release the grippers from the fabric. Do not pull straight up on them, which will yank the grippers out of the fabric and can possibly damage the fabric. Releasing the gripper with a slight outward motion will let it out of the fabric properly and not cause problems. With a little logic and care, fasteners are wonderful and easy to use.

Finally A Solution w/o pins

So we have used cloth diapers for a while on & off we originally used a Snappi Fastner for someone with special needs and they worked ok but they seemed to narrow for use with larger diapers. We really couldn't get a secure fit with pins even after much practice though technically secured with diaper covers we thought there wasn't any way to secure diapers till these were recommended. Though there was a slight learning curve to get best fit. We have used them in many different types of cloth diapers(flats, prefolds, & fitted/contoured, we only had an issue with one fitted but it was the diaper itself as it has snaps near edges-2 day weight that snap together) & various materials and they held really well! We had 2 concerns/suggestions & 1 sort negative for our needs The Negative is the cost, though they secured the diapers we think they would be much better with 2 per side(depending on the diaper & fold) more so when using with special needs, older kids, teens or adults one of our PCA's is great with pins and she uses 2 pins per side, she is the one that recommended these to us. Again the covers do help but we don't want to rely just on a covers. Though we don't use cloth diapers all the time I would think at minimum would want 2-3 sets,1 in use 1 clean maybe a backup well that's $24-36 and if we used 2 per side it's $48-72. Where think we paid $12 for 5 Snappi's & there is a knockoff we haven't tried of these on "A" site $12 for 4 The concerns/suggestions is wish they had a case or something to store them in as the teeth on them are quite sharp & pointy(use caution we have stabbed ourselves). Like the Snappi had part that acted like a guard builtin we currently have them stuck in the bar of soap(did wonder if they would have same benefits) next to the pins we keep near the changing table(originally we used an old pill bottle). The other suggestion & not sure if just us but wish there was better way to grasp it while using it. With all this we still highly recommend them & we have talked to others that use them with those with special needs & they are used all ages and various cloth diapers. We will probably order another set. Will also say GMD CS was prompt at answering our email and overall very helpful and these were shipped quickly

Too sharp

Even though I really wanted to like these and I found they held the diapers on well, I found them too sharp. I cut my finger on one and was constantly worried I was going to do it again (especially with a wiggly toddler).

Baby Boy Approved

I love Boingo fasteners! They’re cute, extremely sturdy, and well designed. I can easily customize the fit and tightness of the diaper. As the mother of a baby boy, I struggled with the Snappi fasteners because bottom hook always needed to go right over his private parts. Because of this, I never hooked it securely, which resulted in a loose fit. But with the Boingo fasteners, I can secure the prefolds in the upper corners, like pins, and completely avoid hooking anything near my baby’s manhood. Note: Boingo fasteners are sharp! I’ve accidentally pricked myself a couple of times while diapering. Nevertheless, they’re my favorite.

Not a fan

I had high hopes for these diaper fasteners. I love the idea. They were very difficult to stretch. They do not have a good place to hold on to as you stretch them. The hooks are so sharp that in trying to put them on you end up cutting your hand.

Beginner friendly fastener

Used these with my older kids when they were in diapers and using these now with preemie twins (prefolds/half flats with wraps). Big fan of how I can use just one (for now) to secure a diaper while little baby legs are kicking wildly about.
