    We have used these to hold our pool cover in place, easy to open and seem good quality so far.

    4.0 out of 5 stars Good with small openings

    Used to secure a canopy to a garden swing seat. The only thing that has worked for me in the gales that can lift ordinary canopies sky high, almost.

    Used so far in DIY/gluing and to keep a protective cover in place whilst I completed a messy task.
    Well made, sturdy and very easy to use. Fit in position easily and are easy to remove.
    Happy with the overall quality and performance.

    Received a very small box and was surprised to see the size of the clamps but they open wide enough for my uses and are quite powerful.

    Well made plastic clamps – useful size – have already been used extensively. Excellent !

    I bought these to keep a table cloth on a stall and they are sturdy without being too hard to use with my arthritic hands. Perfect and not too big. Excellent item.

    Really good quality, robust – bought to hold a cover over our kid’s swimming pool that kept blowing away.

    Great spring clips have used on several projects and end tips have remained in place delighted with these clips

    Got these clips to tie down a cover for my new garden furniture this winter. Really strong sturdy grips. Work well and would recommend

    I originally purchased these to help with our honey harvest as I needed something to hold the cheese cloth to the bucket. They did this job perfectly but have since used them for securing our frames from the hive into the honey spinner, the kids have used them for den building, we have used them to hold a tarp up to create shade in the garden and my toddler enjoys trying to open and close them.
    They can packaged really well in a cardboard box which we use to store them when not in use, it keeps them nice and neat.
    The clamps are very strong and can hold a decent amount of weight! The beeswax and honey that is scraped from the hives frames is very heavy but these were up to the task.
    They are easy to clean in warm soapy water and we haven’t had any issues with them going stiff after drying ( after all honey is stubborn)
    Good value for money and I will purchase again to expand our den building kit!

    I use these to keep cover on my pool they are by far the best, very strong, great grip doesn’t rip cover just keeps it in place. I would 100% recommend

    These are generally good value for money but after a couple of use’s the orange flexible tips just bend and fall off. The clips still work but the pinched area is reduced. Shame really but I won’t be buying them again.

    Spring is quite strong, yes they are plastic but sturdy feeling plastic. Little gripper teeth hold things securely. Used for hot glueing camping knives and forks back together.

    Good product, would buy again.

    Great product this is my second time off ordering as found that they are also great For putting my lights round my gazebo.

    I was sceptical, especially with so many different versions of this product available, and a wide range of prices.
    These arrive quickly, packages great, and work perfectly. I have kept the box, and simply arrange them as I received them after the market has finished.

    Good value product.

    I bought these to attach a stronger cover to the poly tunnel. They are smashing, easy to use and very strong and secure. There are different sizes and the ones I got were 4.5 inch which was perfect to hole the cover onto the round steel frame. I have no hesitation in recommending this item. It was delivered within a couple of days.

    Perfect for holding curtains tight on our gazebo. Wide enough to grip onto metal the frame. Very sturdy.

    Golden Review Award: 4 From Our UsersNot bad strength and grip on these small but mighty clamps. As a part time blade maker, I am mainly using these to hold knife scales to the knife itself. Having a good set of clamps for this is essential. So I got some delivered. 13 for 8 clamps. Equivalent of 1.65 per clamp which is great value. Don’t get me wrong. These are not as powerful as some of the other clamps available from the top brands. But they are such great value that it’s hard to ignore. Full marks for the clamps. Super.

    I use these for so many different things, so much so that I keep some in my car so I have them wherever I am (home, work, allotment, etc). They are robust. Jaws open up to about 4cm. I’ll never be without a supply of them now, especially at the price/quantity they are sold at.

    These clamps are excellent – well made, sturdy, well sprung yet easy to use. Far better than I’d expected and strongly recommended.

    Hard to tell how durable will be as have just got but they certainly appear good.

    Exactly what I needed. Big enough to keep my chair cover in my garden firmly on over winter!

    It’s not often my expectations are exceeded in this case by a mile. Seriously strong clamps, I am using on a bag holding garden furniture cushions.

    Golden Review Award: 7 From Our UsersFor the price, I’m really impressed with these! We lost one of the orange rubber feet during 70mph winds but all considered, I’m genuinely surprised that was all the damage inflicted from holding a tarp over daughters trampoline!

    Do check the sizes that you are ordering, especially how much they open up! Easy to order a size smaller than intended but don’t let that put you off. I will be ordering more when I need them

    These spring clamps were excellent whilst holding on the cover to my mobility scooter whilst winds of 84 mikes an hour were whistling around the garden for the day and night following a storm. Brillia

    Good strong grip for the size. OK price point. Beware plastic pongs a bit when first opened, left in the shed a couple of days and was then fine.

  41. MUQCarlkowwk says:

    Really strong wide grip and can be angled up/down to apply forward/back pressure. A good buy.

    High quality

    Whether this is a sign of poor quality plastic who knows but they did the job I purchased them for so happy.

    Parcel arrived on time and items are excellent .Apart from being a useful second hand for holding things when doing jobs on my own, they are great for hand exercises!

    Golden Review Award: 2 From Our UsersI love how they hold things when I need them to stay put. Great value on this. I am messy with wood glue and I am very happy that these did not stick to the wood when I over glued them. 😀 I highly recommend!

    Golden Review Award: 2 From Our UsersUsing these to hold up some solar light strings and they do a good job. Grip is strong enough to hold the lights in place, but not so strong that you need to be a strong man to open them. So far they have been durable and time will tell if they go brittle in the sun or the mechanism rusts.

    Golden Review Award: 2 From Our UsersNeed quite a bit of pressure to open, but grip really well. I used them to fix shading netting to outside of greenhouse (Halls)- worked really well. Cant imagine any wind/ weather would have shifted it with these clips on. Have given 5 for durability but have only had them a short time. Looking at them tho, I think they will last a long time. Goodbye to my makeshift clothes pegs- glad I bought these.

    Golden Review Award: 10 From Our UsersBought a pack of these to fasten down the covers on our BBQ, parasol and garden furniture as the strong winds we’ve had recently had caused the covers to billow and stretch. The clamps are solid and grip well if you get a good fistful of the vinyl material and twist it round. The rubberised feet adapt to the surface and grip tight as the springs are strong. The only point of concern is inside 3 weeks one of the rubberised feet keeps coming off one of the clips, it can be refitted but it’s annoying. Otherwise it’s all good.

    We bought these to keep the cover on our outdoor furniture. The recent windy weather had been driving us mad, we’d tried everything to weigh the cover down but nothing worked. These clips however are a dream! Very strong but easy to use (not stiff to open and close) I would highly recommend them

  51. Victoria Woollaston says:

    Excellent for securing fabric layers to a table when quilting. Strong and easy to use.
    As far as durability is concerned, have only just purchased them so will see how they work in a few months.
    Reasonably priced product though!

    Golden Review Award: 3 From Our UsersBought these to baton down the waterproof cover for my outdoor ratan table and chairs. The clamps are clipped over the chair backs to hold down the waterproof cover. They have remained secure during strong winds and heavy rain. Very pleased with them, as smaller clamps I tried unclipped during strong wind.
